<p>A triglyceride-to-fuel conversion process including the steps of (a) prec onditioning unsaturated triglycerides by catalytic conjugation, cyclization, and cross-link steps; (b) contacting the modified triglycerides with hot-co mpressed water containing a catalyst, wherein cracking, hydrolysis, decarbox ylation, dehydration, aromatization, or isomerization, or any combination th ereof, of the modified triglycerides produce a crude hydrocarbon oil and an aqueous phase containing glycerol and lower molecular weight molecules, and (c) refining the crude hydrocarbon oil to produce various grades of biofuels . A triglyceride-to-fuel conversion process further including the steps of ( a) carrying out anaerobic fermentation and decarboxylation/dehydration, wher ein the anaerobic fermentation produces hydrogen, volatile acids, and alcoho ls from fermentable feedstocks, and the decarboxylation/dehydration produces alkenes from the volatile acids and alcohols, respectively; (b) feeding the alkenes to the cyclization process; (c) feeding the hydrogen to the post re fining process; and (d) recycling the aqueous phase containing glycerol to t he decarboxylation/dehydration process. A biofuel composition including stra ight-chain, branched and cyclo paraffins, and aromatics. The paraffins are d erived from conversion of triglycerides. The aromatics are derived from conv ersion of either triglycerides, petroleum, or coal.</p> |
