Refining Biocrude

You seem to think that quote on vegetable oil to gasoline, diesel and propane is mine. It isn't. Just a little Google pulls it up.

Yes, you are correct. Our process is the key. It produces the quantity and quality of biocrude that makes it profitable.
The future is now.
"A laboratory process for studying the hydrocracking of vegetable oils in a high-pressure batch reactor is described. The main goals of this study concern the transformation of soybean oil (used as a model) into gasoline and diesel fuel fractions while limiting polymerization and coking. Gas analysis and high-resolution chromatography of two liquid fractions resulting from vacuum distillation were used to determine the main steps in the hydrocracking process.
For this initial study of the general process, the three types of hydrocracking used were thermal hydrocracking and hydrocracking in the presence of an oxide or of a dualfunction catalyst (hydrogenating/cracking). In the latter case, hydrogenation of the double bonds of the lateral chains of triglycerides was observed during the heating of the reactor to about 673 K, at which temperature actual hydrocracking begins. At this temperature, the decarbonylation/decarboxylation of fatty acids (coming from the cleavage of the ester bonds of the triglycerides) is observed together with a marked hydrogenolysis in the presence of a metal catalyst. The main result of this is the production of alkanes having the same linear structure as that of the initial fatty acids. The overall weight percent of conversion may reach 83% under the right temperature and pressure conditions, including the percent of gas fraction (CO, CO2, C1-C4)."
