[biofuel] Re: Biodiesel Properties???
You will find details of properties of biodiesel at various locations that list the ASTM standards. In terms of energy, fossil diesel is about 130,000 BTU/gal and plant based biodiesel is about 120,000 BTU/gal. Animal based biodiesel is slightly less at 115,000 BTU/gal.

[biofuel] Re: Burbank Cactus Catalog
A hundred tons per acre per annum sounds a lot to me. In the UK short rotation coppice can achieve about 16 tons per hectare (6.5 tons/acre) so a yield of over 15 times this seems hard to believe. Eucalyptus in Uganda or Hawaii can achieve 55+ cubic metres/ha/year (ie less than 55 tons) and in terms of biomass production that is pretty impressive.

To get 100 tons of biomass out of an acre WILL REQUIRE at least 100 tons of some kind of inputs - in this case surely mostly WATER. Even if the harvested weight was not mostly water, the biomass weight MUST COME FROM SOMEWHERE, it doesn't just 'happen'. At some point, the 'GOOD CULTIVATED SOIL' will become depleted without an equal amount of nutrients/minerals returned to it. Putting 100 tons of petrochemical fertilizer on any crop to make biofuel is not a very sustainable approach, and will only make sense to study groups, conference planners and petroleum refiners.

[biofuels-biz] Re: Burning sunflowers
Todd, when I was a student in this department there was quite a bit of work being done on the pyrolysis of coal. I suspect this is what they are talking about in this paragraph: Waste pyrolysis oil is currently burned as fuel, but this can be quite polluting, said Dr Dupont. Our system would still make use of its energy potential, while allowing the often noxious chemicals in the oil to be more easily controlled. i.e. 'waste' oil from a totally separate process, not the co-product of the steam reforming of sunflower oil. H --- In biofuels-biz@yahoogroups.com, Appal Energy [EMAIL PROTECTED] wrote: http://reporter.leeds.ac.uk/483/s3.htm All a bit elusive... quote: Most methods of producing hydrogen burn another fuel for energy, which itself creates pollution - carbon monoxide, nitrogen oxides and other emissions, said Dr Dupont. Our catalyst uses oxygen from the air to heat up naturally, and this heat is used to reform the oil with steam to create hydrogen. The excess carbon dioxide is taken into the second catalyst, then released for storage or use in other chemical processes, ensuring that damaging levels of CO2 aren't just put back into the atmosphere. Oxygen from the air to heat up naturally... Interesting. I wonder what their loss rate of catalyst, or energy cost to restore it if needed, or life cycle energy cost to refine it. They mention pyrolysis in a latter paragraph. Wonder where they get the damaging levels of CO2? If they were using the pyrolytic fuels from the process itself to perpetuate stripping (not creating) hydrogen they would be carbon neutral at worst, erego no damaging levels of CO2. Not to say that CO2 recovery is not intelligent, as it could be used to produce methanol as a useable byproduct, among other things.

[biofuel] Re: Diesel engines vs. gasoline engines
Where I live there is no competition between petrol an diesel. The roads are often flooded for several days at a time and a damp petrol car won't run. I always look for vehicles with the air intake on the top of the engine as well. Work-wise petrol engines can't match the torque characteristics of a diesel engine, so floods or not, it will always be diesel for me.

But even when I financed my studies by driving taxi in Stockholm some 40 years ago, the diesel taxis engines last 3 to 5 times longer than gasoline. The famous London Cab is a diesel car. In todays diesels it is even difficult to know as passenger, if it is diesel or not. As driver you know because of the heating light before startup (5 seconds). It is no real considerations, the diesel engine will last longer and work better. Hakan At 01:11 AM 12/11/2002 +, you wrote: I live in city of about 130,000 people. I'm looking at buying a diesel and using biodiesel for fuel. I have a question though about the praticalities of owning and using a diesel in an urban environment. I wasrecently warned against buying a diesel engine-based vehicle if the vehicle's primary use is mainly short trips (i.e. in a city). The main reason given was that diesels are meant to be driven long distances (i.e highways). To drive a diesel in-town on short trips, is to basiclly have a vehicle that dies out sooner than a gasoline powered vehicle. My question is whether accelerated deterioration would be linked to carbon build-up within typical diesels (my understanding is that biodiesel eliminates this build-up) Does anyone know or can explain the differences between the two types of engines and tell me whether there is any merit to this caveat? Are there any other considerations needed to be kept in mind when thinking diesel within the urban framework?
