Biofuels production from bio-derived carboxylic-acid esters

A process for producing biofuels compounds directly from carboxylic acid esters recovered from a fermentation system is described. The process involves taking a fermentation broth that has been reduced to a dry powder containing free organic acids; reacting the carboxylic acid in the powder with an alcohol solvent under a CO.sub.2-containing atmosphere in substantial absence of any other acid catalyst at a reaction temperature and pressure that corresponds to supercritical, critical or near critical conditions for at least one of the alcohol or CO.sub.2 to synthesize an ester, then subjecting the ester to either hydrogenolysis or hydrogenation to form a biofuel.
