Re: [Biofuel] B100 and jet fuel
I agree that B100 would probably burn well in a turbine. As pointed out in a previous post turbines will run on a wider range of fuels than almost any engine (except a steam locomotive??) But knowing something about the aviation industry I will hazard a guess that this will be the last place we will see eventually going over to biofuels. Hell long after the automotive industry went off tetraethyl lead you still had plenty of high compression aviation engines running it. Change comes about very slowly in the aviation circles. Maybe when the LIM cycle engine has been around for twenty years and general aviation pilots begin to hear about the guy who has one a few fields down the way we will begin to see some acceptance and trust of biofuels for aviation use. While airlines may benefit from fuel cost savings they will not risk running unproven fuel, heck they won't put fuel drained from tanks back in an aircraft. Engine manufacturers would have to run thousands of hours on the alt fuel before they would give approval to it's use for commercial aircraft use but they don't stand to gain anything from reduced emissions or airline X's reduced fuel costs so why would they do it? I'm not holding my breath on this one.

Re: [Biofuel] B100 and jet fuel
Thanks for the info. I've read it, downloaded the study reports, read them, and passed them and your email on to the individual that was looking for this information. Good solid data. I think that with modification of the biodiesel transesterification process the TAN might be reduced, and as B20, looks like a potential reducer of dependence on petro products. Even at 20%, the total amount used by the airline industry would be reduced significantly. The CO(sub)2 numbers are impressive! Certainly worth further study and experimentation Thanks again! doug swanson Alan Petrillo wrote: Greg and April wrote: The short answer is no. The short answer is _yes_.

Re: [Biofuel] B100 and jet fuel
Dear Alan,Greg and Petrillo Here in Brazil , the research that had been realized for military to replace Jet fuel using BioD in 1980 was done with positive results, but the details are not much known as less study were conducted at the time . By using low molecular fatty acids ester ,the BioD need to be engineered to be very good additive.Surely there are problems regard to viscosity.Small jet here are able to run with alcohol fuel and hence BioD will be also positive , may not be 100 percent. sd Pannirselvam Brazil On 9/4/05, Alan Petrillo [EMAIL PROTECTED] wrote: Greg and April wrote:The short answer is no.The short answer is _yes_.Baylor University did some testing with B20in their Beech King Air 90, and found that it did just fine.

[Biofuel] B100 and jet fuel
A neighbor who recently retired from the airline industry has been asking me lately if there's a biofuel that can be substituted for jet fuel, and although I didn't know at the time, I've done some research since, and see that jet fuel is a variant of diesel. Any one out there know what kind of variant jet fuel is of diesel, (I seem to understand that it resembles kerosene) and can jet fuel be grown? doug swanson (in Ellijay, GA, not far from Atlanta GA, where gas prices spiked up to $6.00/gal. for a few hours yesterday) -- All generalizations are false.
