Assignee:

Texaco Inc. - San Ramon CA

International Classification:

C10L 1/18

US Classification:

44436

Abstract:

The instant invention pertains to new processes which produce an energy source effectively, efficiently, and in a more environmentally friendly manner. The process comprises hydrolyzing a lignocellulosic feedstock to form lignocellulosic hydrolyzate and a hydrolyzate residue. The lignocellulosic hydrolyzate is treated to produce hydrogen. The hydrolyzate residue may be reacted with hydrogen in the presence of a catalyst to yield the energy source.

Abstract:

The present invention provides an improved method for solvent liquefaction of biomass to produce liquid products such as transportation fuel. The method uses a novel solvent combination that promotes liquefaction relatively quickly, and it reduces the need to transport large amounts of hydrogen or hydrogen-carrying solvents. It operates at lower pressure than previous methods, does not require a catalyst or hydrogen gas or CO input, and provides very high conversion of biomass into a bio-oil that can be further processed in a petroleum refinery. It also beneficially provides a way to recycle a portion of the crude liquefaction product for use as part of the solvent combination for the biomass liquefaction reaction.
