WET OXIDATION OF BIOMASS

摘要

A process for producing a transportation fuel from a lignocellulosic feedstock comprising subjecting a stream comprising lignin to a wet oxidation that produces low molecular weight carboxylic acids. These carboxylic acids and/or the corresponding esters are fed to a hydrogenation reaction or gas fermentation wherein they are converted to an alcohol. Heat from the wet oxidation may be supplied to any stage of the process in which heat is introduced.
