Re: Latest Jet Aircraft are to Fly using Coal, for Fuel (Mike Kremer)

I've done coal chemistry for Occidental Petroleum. I don't believe a word of it - especially the non-coking nature of the fuel and its low sulfur content. The chemistry as described is flat out impossible, as is the nature of the product.

Coal is almost all aromatics with a grievously low H:C ratio. Nobody has ever been able to decently, much less economically, hydrogenate the unsaturation. Mixed pyrolyses are nightmares for both product and waste disposal.

Coal + water => CO + H2

CO + H2 + catalyst => methanol, CH3OH

methanol + ZSM-5 catalyst => C8 aromatics stream + water

BTX and other very cheap, very high octane aromatic streams are banned from fuel for their "ozone-forming potential." Suck off an Enviro-whiner, pay $(US)3/gallon at the pump.
