ABSTRACT:
A process for the direct conversion of lipid biomass fuel stock to combustible fuels include the steps of hydrolyzing a lipid biomass to form free fatty acids, catalytically deoxygenating the free fatty acids to from n-alkanes, and reforming at least a portion of the n-alkanes into a mixture of compounds having the correct chain length, conformations and ratio to be useful as transportation fuels. The process exhibits an overall energy efficiency of at least about 75%, wherein energy efficiency is calculated as the lower heating value of the produced transportation fuel over the sum of the lower heating value of the process reactants and the total energy input into the process.
