Abstract:
1. A process for preparing solid biomass for slurry processing comprising the steps of: grinding the solid biomass to a small particle size, the solid biomass comprising lignocellulosic material that comprises lignin and cellulose; adding a dispersion agent to the solid biomass, thereby creating a suspension phase of the lignocellulosic material, wherein the dispersion agent is a polar organic solvent selected from the group consisting of a large organic acid, a polar-protic solvent, a polar-aprotic solvent, an oxygenate, and mixtures thereof; and contacting the suspension phase with a solid hydroprocessing catalyst, having a zeolite deoxygenation function, that causes the lignocellulosic material to react and produce a process stream comprising oxygenates and aromatic compounds.
