PROCESS FOR PRODUCING FURFURAL FROM BIOMASS

PROCESS FOR PRODUCING FURFURAL FROM BIOMASS

A process for making furfural, derivatives of furfural, or both from biomass is described. The biomass feed is optionally conditioned to obtain a moisture content of 25 wt % or less. The biomass feed is ground to form particles having a particle size in a range of 0.02 mm to 7 mm with 5 wt % or less...

Zusammenfassung:A process for making furfural, derivatives of furfural, or both from biomass is described. The biomass feed is optionally conditioned to obtain a moisture content of 25 wt % or less. The biomass feed is ground to form particles having a particle size in a range of 0.02 mm to 7 mm with 5 wt % or less being 75 microns or less, and an average aspect ratio of 0.4 or more. The ground biomass feed is blanketed with an inert gas having an oxidant or oxygen content of 5 mol % or less. The ground biomass feed is reacted in the presence of water, a water-immiscible organic solvent, and an acid catalyst to form a reaction product mixture comprising furfural, derivatives of furfural, or both.
