Abstract
A process for hydrocracking biomass, and the hydrocarbons produced therefrom. A feed stream having free fatty acids, fatty acid esters, or combinations thereof is contacted with a first catalyst under hydrogen pressure and heat. The hydrocarbon product stream which is comprised predominantly of n-paraffins is separated into heavy and light fractions. The heavy fraction is contacted with a second catalyst under hydrogen pressure and heat to produce an effluent stream which is combined with the light n-paraffin fraction to form a unique middle distillate product useful as a diesel or jet fuel.
