Thanks for the replies
Yes the magnetic mixer as you both describe does sound like something
I could build. At the moment I better focus on the basics.
I need to work on my lab skill. Today we found out a ton of science
associated with biodiesel. Lots more info sunk in as we actually do
this stuff. Not that I didn't expect this. Tomorrow we will have a go
at it again. My wife and I are on page one.

I have read about this process from a big picture perspective. Now I
learn the detail.

I can't believe I forgot to bring a scale home for my first test
batch. Oh well.

We are still in the process of calculating the amount of lye to mix
with the methanol. As soon as we figure this out, I imagine the next
obstacle will present itself. Par for the course, no?  This is ok. We
are patient. This is really the only way to learn. "Try it." As
everyone here says.
We are game.

Re: [Biofuel] Americans ugly and otherwise...

2005-10-15 Thread Zeke Yewdall

I saw an analysis somewhere before the last election, which pointed
out that the two parties in the US are really made up several factions
that really have little in common.  For example the Republican party
is made up of fiscal conservatives, social conservatives, and
neo-cons/war hawks.  These groups are not at all the same (and many of
the fiscal conservatives are pretty bewildered by the direction Bush
and Co. are taking the country), yet they are all classified as
republicans.  Similar, the Democratic party is made up of at least two
or three disparate sub-groups.  These subgroups have to claim to
represent one party or another to get anywhere in our political
system, but it would be very interesting (and perhaps more interesting
to voters too) if there were more like 6 parties, instead of just two
conglomerations.

Re: [Biofuel] Cleaning 44 G Drums

2005-10-15 Thread Zeke Yewdall

My drums have come with palm oil and stuff so it hasn't been an issue,
but I have used biodiesel for cleaning other stuff covered with
petroleum oil products and it works good.  You'll end with some
engine-oil contaminated biodiesel, which can be diluted and used as
fuel, if you don't mind a little smoke. I think the pollution from
burning the oil is probably better than trying to dispose of the
engine oil residues any other way though -- certainly can't be
composted or anything.

Re: [Biofuel] Start Up Problems

2005-10-15 Thread Chris




Everything sounds good, although perhaps you could 
use 2.5 gms lye.  You never say that you pull off the biodiesel from the 
glycerol though.  It is so obvious that you may have not mentioned 
it.  But, if you are not doing it, that's it.  What does the biodiesel 
look like after separation?

  Oil - supermarket virgin oil
  Deep cooker filled with water with thermo

  Have tried lots of combinations re

  amounts of methanol 200ml to 250ml per

Hi Mike,
I am responding to this post as a matter curious interest.  I wonder if 
this country would be in better shape if there were no such thing as the 
Party system. For example, I have steadily been drifting apart from any 
affiliation and instead just looking at the issues, hearing out and 
researching them, and deciding what my view point is, and I no longer 
care if my new perspective crosses a party mentality whatsoever.  I am 
usually just a listening post anymore, and spend more time thinking out 
what I have heard to dissect it from several perspectives.  I find this 
to be rather eye opening and enlightening but also scary as some of 
those sacred beliefs can get trashed and replaced.  Anyway I was just 
wondering what your response to this might be as I respect your opinions

Re: [Biofuel] Start Up Problems

Something I keep hitting over and over in all my prelim test batches
(Still haven't made one any bigger than a liter...): How's your
humidity, and are you absolutely certain that your weights for the lye
are accurate?

I was having some huge problems with emulsions on a shake test, and
with the scale I just recently purchased (Jeweler's scale, up to 500g)
I discovered just how inaccurate my old one was; I was using way
too much lye, and taking far too long to measure it out. It was
absorbing a great deal of water from the atmosphere (70%+ humidity is a
constant here). 

How big are your test batches? The full 2L capacity, or are you only
doing 1L batches? I eventually moved to smaller batches so I could
measure out my lye quicker, it helped a bit. My current test batches I
mix up in a small 400mL Mason-type canning jar, 300mL of oil to about
75mL of Methanol, and just use a hot water bath to bring it to
temperature, shake it for ten or fifteen minutes, put it back in the
bath for ten, shake fifteen soak ten, and so on for about an hour and
half. Produced some very clear, clean-looking results so far. >.>
Have you tried heating up your wash water before doing the shake
test?  That also helped... I'm slowly, very slowly progressing
back up to full sized test batches while I gather parts.

Hoped some of this helps!

[Biofuel] Start Up Problems

2005-10-15 Thread Peter Currie




G'day group
it is with great embarrassment that l have my first 
post. For 3 months l have been doing test batches (lost Count how many) and 
still cannot past shake test.
Methanol - From a drag racers 44 gallon drum - best 
apparently
Lye - Tiny pearls 99+ - fresh - then 
flake
Oil - supermarket virgin oil
Deep cooker filled with water with thermo (bottling 
type to 120 deg. C )
Drill stand above
2Lt glass jar tall with narrow neck with screw top 
lid with hole for paint stirrer
Have tried lots of combinations re 
mixing time (1hr to 2.5 hr)
Mixing speed - slow 
to fast
amounts of lye - 2.7g to 4.2g per lt
amounts of methanol 200ml to 250ml per 
lt
types of oil - canola , blended edible all say 100% 
unused
After process the product separates nicely and 
after waiting 12-24 hours do shake test with rain water (all l have) usually it 
takes hours to separate with a thick layer in-between of white fluffy cloud like 
stuff (.5 inch thick)
The pearl variety of lye dissolves quickly but is 
hazy whereas the flake is crystal clear. Am heating oil to 55 c then adding 
methoxide then stirring maint temp throughout. Have read and reread JTF site and 
archives but nothing leaps out as obvious, my process seems correct, my 
materials seem correct but l'm starting to feel Very stupid. Is there something 
on this side of the planet that l'm not aware of?. Also would be very keen to 
talk - SEE setup working in Melbourne Aust. I'm in the Dandenongs. Any advice 
would be appreciated, thankyou
Regards
Peter from Oz

Re: [Biofuel] Multi Fuel Engines

You know, reading that and several other concepts and proven designs has put an idea into my head.

I was doing some library research earlier today, and stumbled across
the Deltic opposed piston engines. I looked into those, and was just
utterly floored. "Like, whoa." is what the guy sitting beside me in the
library told me I said. Those things rocked in some serious ways, with
only a really complicated crankshaft balancing system keeping them from
being really workable on a widespread basis. Ideas immediately started
pouring through my head on how to revive the OP engine design.

Then I log on to check my e-mail, and see this. "Like, whoa" all over
again. I read everything they have on their site. And the thought hits
me.

A cam-driven opposed cylinder engine. Cam at one end, cam at the other,
12 cylinders in a round block, 24 pistons riding the two cams. Utterly
and completely removes the crankshaft synching issues inherent to the
OP design. Low/No exhaust pulse, no valve rattle, no valve timing,
drastic moving parts reduction, size reduction, no flywheel needed;
with all the reciprocation operating in a front-back orientation, there
wouldn't really be any piston pulse to deaden; the mass of the car
would do it just fine. Smooth, even rotations, approximately 12 power
strokes per revolution to even out the power application. Use small
bore/long throw pistons in your cylinders and it would probably even be
more incredibly efficient than an inline 3-cylinder.

It would be perfect for that "slow burn" combustion of compression ignition engines.

Perfect for diesel. Even more perfect for BD.

I want to build it. I need to build this.

And all I can think now is "God I'm a geek" :p

Re: [Biofuel] methoxide solution

2005-10-15 Thread JJJN

Hi Brian,
A magnetic mixer is just a small DC motor that is variable speed that 
rotates a STRONG magnet under a platform. You then place in the jug PVC 
or Polyethylene coated Magnets and screw the lid on.  Turn on the mixer 
and its like a blender inside.  If you do use Red devil lye it can get 
reallly hot fast but I never melted or expanded to much. I rather 
prefer the slower dissolving lye with this type of mixer.  I got mine 
free as it was replaced with a newer one and was gathering dust. when we 
moved our lab my good friend the chemist gave it to me rather than throw 
it away.  They would be real easy to build and the part that goes in the 
Methoxil is cheap at NW Scientific Supply I can give you the email if 
you want it.

Aw, come on!  You mean I don't have to sterilize my soil first, then 
pile on a bunch of "mineral supplements", herbicides and pesticides in 
order to get a good crop?  Who is gonna make money composting?

http://foodforeveryone.org/vegetable_gardening/20/what-is-the-mittleider-method

These people make it sound easy.  However, if you read the Mittlieder 
book you'll discover its all about perpetual dependence on 
fertilizers, herbicides and pesticides.  It's a "one size fits all" 
method.  Here are some quotes to boil your blood:

"Although soil conditioning is good, precision placement of 
properly 
balanced commercial fertilizers is more efficient."

And:

"Most commercial fertilizers must be properly balanced and then 
supplemented with micro-nutrients for optimal effect.
Apply fertilizer before you plant and several time thereafter. 
Use fertilizer to control weeds between plants."

Oh boy!  I've spent the last two years trying to get AWAY from that 
kind of mentality and we've seen good results this year.  (We've given 
away better than half of what our garden produced, simply because we 
could neither eat it nor store it all.) Part of the problem, however, 
is that there is a HUGE amount of propaganda disseminating among the 
public concerning the supposed superiority of industrial agriculture, 
even on a garden scale.

Re: [Biofuel] methoxide solution

It sounds like a great new toy, but believe me - you don't really need
magnetic mixer to prepare methoxide solution :) If you want to playwith it, that's a different matter, but it's quite enough to use
ordinary thick plastic HDPE bottle carefully swirling it. It takesa bit of time, but hydroxide must be completely dissolved.

I remember using those things  in high school Chemistry class, they were awesome!

I've often contemplated (recently) how to make one of my own,
improvised kinda; the ones I remember were rather small, and I'm
thinking of using it as a way to keep my methoxide mixer pretty much
sealed down to as few cuts as possible in the plastic; a magnetic
stirrer would let me reduce it by a mixer shaft opening, after all.

>From what I can tell, in essence they're just a pair of rotating
magnets; one is directly rotated by a motor, and the other is rotated
by the first's magnetic field. You'd need a much stronger drive magnet
than stirrer magnet, I'd imagine, and a home built one would probably
only have a few inches of effective separation distance, but it could
probably be done. Rig up a motor on a dimmer, get an HDPE coated
stirring magnet, and go at it?

Sounds like fun, to me. :p

Lye is hygroscopic; it absorbs water quite readily. 

Yeah, I'd suggest waiting for it to quit raining, as ambient humidity
increases will throw off your measurement of lye on both a mass and
volumetric basis because of absorption into the pellets or grains. 

Now if the humidity in your house is still low, you could always
quickly measure it out and put it in a sealed container with your
methanol, then hustle outside to mix it; I use Mason jars to mix my
methoxide in for test batches.

Funny you should mention this... In the last half hour it began
pouring rain. I ran outside to get the firewood covered and now I am
soaked. Meanwhile my wife got a roaring fire going in our heavily
modified wood heater. It is now warming and drying us.

I do recall that that ambient humidity messes with the methoxide
mixing. Should I wait until the rain quits to continue with the
experiment?

Re: [Biofuel] Resource windfall!

Copper and vegetable oil: "I'm not so worried about the copper but
what the copper does to the fuel. Did you ever check what happened toyour fuel properties like oxidation stability and acid value? A lotof research has been done in Germany on VO (and biodiesel) fuelproperties, and who I consider as the leading experts clearly warn
against using copper in connection with VO because of the catalyticeffect it has on the VO. The laboratory ASG Analytik-Service(http://www.asg-analytik.de), who were involved in the research
leading to the "Rape Seed Oil Fuel Standard", says that just a fewPPM of copper in VO will change the oxidation stability... [In SVOsystems] with a catalytic metal, I think you have the best conditions
and environment for decomposition of the VO, and the effects it hason the fuel properties again have an impact on the engineperformance, engine conditions (lifetime) and emissions composition."-- Niels Ansø, Folkecenter, Denmark

This is what we were looking for. We even attempted to find the

complicated for us. A trip to town would be simpler we figured.

Re: [Biofuel] methoxide solution - missing scale

Hey Brian

I've run into problems with measuring lye myself, and ultimately
managed to work out a loose but somewhat workable way to measure out
the lye by volume. It produced some of my best results to date, too, so
I think I'm safe to share it with yas.

Sodium Hydroxide has a density of 2.1 grams per cubic centimeter. Since
a cubic centimeter = a milliliter, you can use your beaker with mL
scale on it to measure out the lye volumetrically. For a test batch
with virgin oil it's going to be some incredibly small number; under
2ml, I believe. I was only doing a 300mL test batch, so I needed under
a milliliter of NaOH.

Using the density of NaOH, convert your titrated grams into
milliliters, then measure them out volumetrically and add to your
methanol as per normal. I'd suggest erring on the side of caution when
measuring it out though; unless your beaker is graduated in .01mL
increments it might be hard to get a truly accurate volume.

I decided when I tried it to err on the low side, as an incomplete
reaction I've read can be reprocessed but too much lye is worse news on
the washing step.

In the end though, all these guys on the list are right; there's no
substitute for a good, accurate gram scale. Just picked on up myself,
in fact, measures out to .1 grams with a 500g capacity.

Good luck to ya!

I think you are right. If you can take a look at a post I just sent
under a modified thread name "[biofuel] methoxide solution- missing
scale" you will see that real world issues have already hit us. This
"doing it" phase has made me realise that I forgot a basic tool, the
gram scale. Dang it. Anyone that can help us figure out how to measure
the lye with no scale would be looked upon as a living god by us.
If not I will go find a scale and start again tomorrow.
Thanks again

[Biofuel] methoxide solution - missing scale

Hi biodieselers
I am here with my wife in our kitchen working on our first titration of WVO.
We have determined through heating a sample of WVO that no water is
present. We have found a soil test kit that has several types of
litmus paper. We did several tests of the litmus to determine if it
was still fairly accurate by testing a light solution of lye water,
household water, distilled water and finally battery acid. We have
compared the litmus paper color change and are satisfied that we can
tell the difference in major pH scales. By the way, this
experimentation is too much fun.

We have several browser windows open to the archives and conversion
tables for reference. It seems the first thing I forgot to collect for
this first test is a gram scale. We live 15 miles from town and a
hopeful there is a way to measure the lye without making a special
trip. Or, are we done for the day?

We have a decent thermometer, 1 beaker with ml scale, two syringes
with cc scales, goggles, gloves and lots of excitement.

Our question is this: Can we do this first step without the scale?
What else are we forgetting if a trip to town is needed?

Thanks for your help.

It sounds like a great new toy, but believe me - you don't really need
magnetic mixer to prepare methoxide solution :) If you want to play
with it, that's a different matter, but it's quite enough to use
ordinary thick plastic HDPE bottle carefully swirling it. It takes
a bit of time, but hydroxide must be completely dissolved.

Copper and vegetable oil: "I'm not so worried about the copper but 
what the copper does to the fuel. Did you ever check what happened to 
your fuel properties like oxidation stability and acid value? A lot 
of research has been done in Germany on VO (and biodiesel) fuel 
properties, and who I consider as the leading experts clearly warn 
against using copper in connection with VO because of the catalytic 
effect it has on the VO. The laboratory ASG Analytik-Service 
(http://www.asg-analytik.de), who were involved in the research 
leading to the "Rape Seed Oil Fuel Standard", says that just a few 
PPM of copper in VO will change the oxidation stability... [In SVO 
systems] with a catalytic metal, I think you have the best conditions 
and environment for decomposition of the VO, and the effects it has 
on the fuel properties again have an impact on the engine 
performance, engine conditions (lifetime) and emissions composition."

[Biofuel] TEFC Electric Motor Sizing

2005-10-15 Thread Ken Dunn

Hi all,

Still gathering my parts for my processor.  I found a 1 inch clear
water pump that I'm going to use only for transferring the oil.  I
don't know if anyone has a Habitat for Humanity store near them but,
they always have a bunch of motors and pumps at the one near me.

Unfortunately, I can't find any used TEFC motors.  I've resigned to
buying a new TEFC motor for my stir processor.  I'm going to be using
a 55 gallon drum as my reactor.  Looking at some of Todd Swearingen's
diagrams and others, I think I should be able to get away with a 1/4
HP motor.  A 1/3 HP motor is available locally but, I don't want to
waste any energy or money.  Anyone have any guidelines on motor sizes
based on processing capacity?

Take care,
Ken

Re: [Biofuel] Resource windfall!

2005-10-15 Thread des

I've gotten a couple of submersible pump ends (heads?) from a well 
drilling outfit that regularly replaces pumps that die after getting hit 
by lightning.  Only the motor dies, and they had a pile for me to hunt 
through.  Didn't notice anything for above ground, since that wasn't 
what I was looking for.  You may have a similar resource where you live.

I'd guess that above ground pumps can suffer the same fate, though I 
hear of the pump end of the above ground pumps going out first in the 
winter, water freezing and bursting the pump.

[Biofuel] Resource windfall!

I was rooting around under the house recently, trying to find a rumored stockpile of materials left over from when we built the house, and lo and behold I found it.
Or something that pretended to be it, at least.
I now have, in my possession, some several dozen feet of copper piping, elbows, Y-connectors, Ts, and a good number of ball valves for same piping. As well as four 55 gallon drums, all plastic. Also in this little treasure trove was a 1/4hp motor (1730RPM) and a pair of 1/3hp motors (3300 and 1500RPM), a rather large box of electrical connectors, a small mini-breaker panel, and some three thouand feet of 12ga three conductor wire. Around fifty or so linear feet of PVC piping as well, and joints and connectors for that are easy to find. Rock on, I may not really have to buy anything for a processor later.

Just one question, and I haven't been able to find any mention of problems (Though I haven't exactly done an in-depth search yet) concerning using copper piping for everything. Does Methoxide have any problems with it? BD? I know the oil probably won't, and from the use of copper in a methanol condensor I hazard that it doesn't have a problem with it either.

And does anyone know where I can just by pump heads, not full blown pumps?

[Biofuel] Americans ugly and otherwise...





Outside of my little nest here on the East Coast I feel like a stranger
in my own land.  I go to the Midwest to visit family and I cannot and
do not talk to them about politics..  I have come to realize, after 40
years, that they won't and probably can't change.  I prize family above
rhetoric.  I have finally learned it is better, in some cases to be
happy than to be right.  OTOH, I did not live thru what they did: 
WWII, most of them have been working since they could walk, and did not
have the benefits I have had.

My father left Arkansas in his teens, got a degree, was drafted and got
a PhD.  He moved East and saw to it that his childred all went to
college and grad school.  We have all travelled overseas and in some
cases lived and/or worked in the 3rd world.  As Mark Twain said: 
nothing is as deadly to prejudice as travel.

I have to agree with pretty much everything you say.  Except, we have
no real foreign policy, nor do we really have an energy policy.  We
have a bully policy.
No wonder 90% or the world is mad at us.  I don't blame them.

OTOH, the French are not without warts - look at West Africa.  I am
also interested to see what happens with Western Europe with regards to
their economies.
The Western European countries are belatedly realizing you can't just
conjure an economy.  You have to have money before you can have
generous social programs.  This what Germany and France are wrestling
with now.  I personally think a realistic economic base - fewer
regulations in some cases - in France it's pratically illegal to start
a small business, and God help you if you fail - you can expect to
investigated for fraud no matter what happened.  Complain about the
USll you want but you can start a business w/o fear of gaol.  This one
of the thing we do have to offer as a model for other countries.

This country has a ways to go in terms of social programs.  I still
can't believe we don't have SOME form of national health.  The current
system is collapsing.  My sister is a doctor and I can tell you the
current program is failing.  I also believe that we need some form
child care - if both parents must work there must be a safe place for
their children.  Europe is miles ahead of us here.

I rattle on...

They're something of a requirement here in the Southeast. Humidity up

more "normal" shower after I've biked in that heat. 
  
I guess though that I'm weird, cold showers are my preference.
Certainly less taxing on our NG water heater, though. And cool showers
are pretty effective at cleaning if you've been sweating heavily

The chemicals are most probably pure and good quality. Also, lye has
