Hello again Manickh
Hello Keith,
Manickh is fine. No i did not hear about that work at USM but I will
forward it to a friend who might be interested in water removal from
natural latex as an alternative to centrifugation. I seem to have a
problem with diagrams always it is saved in separate folder which can
be uploaded separately without merging. Often i upload both files. If
I recollect the missing diagram refers to a pyrolysis scheme wherein
the rice hulls are pyrolysed to a char first b4 treatment (to make
silica?). Silica is sooo interesting but alas I do not have access to
laboratory facilities anymore since I am retired. So I browse web
instead--came across biofuels only recently. It is excellent and I
get lots of information from it. Steve's post that u could drive cars
on 160 proof ethanol came as a real shocker. I did not know that
20% water does not harm the engine.
WATER INJECTION
During World War II, the military made extensive use of water
injection in high performance piston aircraft engines. Later, water
injection was used by both civilian and military jet aircraft to
provide extra thrust, principally on takeoff. Even today, water
injection systems are available that can be installed in automobiles.
The fact is that, within certain limits, these systems actually do
increase power. Referring back to Figure 2-2, note that the latent
heat of vaporization for gasoline is about 140 Btu/lb and for ethanol
about 361 Btu/lb. Water has a latent heat of about 700 Btu/lb!
Therefore, if a little water is injected into the carburetor in the
form of an ultra-fine mist, the latent heat of the water will cool
the charge and increase volumetric efficiency. In addition, when the
charge is fired in the cylinder, the water will turn to high-pressure
steam and provide additional power due to the pressure exerted by the
steam. There are definite limits, however, to the amount of water
that can be injected. Too much will cause excessive cooling and
misfiring.
The use of water injection with a gasoline fueled engine requires a
separate metering and injection system because water and gasoline do
not mix. Ethanol and water, however, do mix and the benefits of water
injection can be had simply by adding the desired amount of water to
the alcohol in the fuel tank.

I have also learnt that u have
lots of molasses and rice hulls in the USA available at low cost. I
can only conclude that u r sitting on 'green gold'...the fuel of the
future by a long shot. TQ
Well, not me, I'm in Japan for the moment, but I agree. There's a lot
of feedstock just lying around or going to waste or causing problems,
and a lot of potential for growing biomass crops and better biofuel
crops that's hardly begun to be exploited. It's the same here in
japan. Everywhere I guess.

Keith
