Re: [Biofuel] Fwd: Re: Catalytic Fast Pyrolysis, turns biomass into Green gasoline
Hi Kirk Interesting comments from a biologist friend. Hope he is wrong :( Kirk He has a point here: Then converting agriculture to fuel production, after 60 years of saying the food supply cannot keep up with demand, is diabolical subversion of agriculture by the population control mob which wants another excuse for exterminating 90% of the population. I don't think they're looking for another excuse though, they just keep changing what they call it (they used to call it eugenics, for instance). Actually the growth in the food supply stayed 17% ahead of the population growth over the last 30 years. Or so the figures say, but those are the figures for industrial food production, which isn't actually food, it's commodities, grown for money, not to feed people. The food most people eat still comes mostly from small farms (where they haven't been destroyed by agribiz) and city farms, and that doesn't get counted. Farmers lie anyway to outsiders from the city looking for numbers, if they've got any sense, which they usually have got. Anyway, it's not because of overpopulation nor because of a lack of food that so many people starve (852 million officially, though it's more than that), it's mainly because they've been shoved off the land and out of the economy by industrial agriculture, as heavily promoted and enabled by the Rockefeller Foundation, which also has long been the main nest of the population control mob, what a coincidence (and indeed the Rockefeller Foundation used to call it eugenics). Meanwhile soaring food prices, scarcity and world-wide food riots are not (or not yet) due to pressures on the food supply caused by increased biofuels production as so widely alleged, but mainly to soaring petroleum prices. IMHO the question to ask about all the next-generation so-called green fuels techniques being touted is whether they fit the Appropriate Technology model - can you do it at village-level? Probably not, it's more likely to be industrial-scale. People do some lab work and file for some patents and make big claims, pretending it's something that actually exists, but usually it's just investment-bait. The problem with the Appropriate Technology model is that it's so difficult for entrepreneurs and investors to make any money out of it, unlike industrial-scale projects. But if it doesn't fit the Appropriate Technology model it's useless.

In the same issue, James Dumesic and colleagues from the University of Wisconsin-Madison announce an integrated process for creating chemical components of jet fuel using a green gasoline approach. While Dumesic's group had previously demonstrated the production of jet-fuel components using separate steps, their current work shows that the steps can be integrated and run sequentially, without complex separation and purification processes between reactors. While it may be five to 10 years before green gasoline arrives at the pump or finds its way into a fighter jet, these breakthroughs have bypassed significant hurdles to bringing green gasoline biofuels to market. It is likely that the future consumer will not even know that they are putting biofuels into their car, said Huber. Biofuels in the future will most likely be similar in chemical composition to gasoline and diesel fuel used today. The challenge for chemical engineers is to efficiently produce liquid fuels from biomass while fitting into the existing infrastructure today. For their new approach, the UMass researchers rapidly heated cellulose in the presence of solid catalysts, materials that speed up reactions without sacrificing themselves in the process. They then rapidly cooled the products to create a liquid that contains many of the compounds found in gasoline. The entire process was completed in under two minutes using relatively moderate amounts of heat. The compounds that formed in that single step, like naphthalene and toluene, make up one fourth of the suite of chemicals found in gasoline. The liquid can be further treated to form the remaining fuel components or can be used as is for a high octane gasoline blend. Green gasoline is an attractive alternative to bioethanol since it can be used in existing engines and does not incur the 30 percent gas mileage penalty of ethanol-based flex fuel, said John Regalbuto, who directs the Catalysis and Biocatalysis Program at NSF and supported this research. In theory it requires much less energy to make than ethanol, giving it a smaller carbon footprint and making it cheaper to produce, Regalbuto said. Making it from cellulose sources such as switchgrass or poplar trees grown as energy crops, or forest or agricultural residues such as wood chips or corn stover, solves the lifecycle greenhouse gas problem that has recently surfaced with corn ethanol and soy biodiesel.
