METHOD FOR PRODUCING FURFURAL FROM LIGNOCELLULOSIC BIOMASS MATERIAL

摘要

A method for producing furfural from lignocellulosic biomass material is provided, comprising (a) contacting the lignocellulosic biomass material with a mixture comprising water and an organic acid at a temperature of at least 100° C. and a pressure of at most 10 bar (absolute) to obtain a first liquid stream comprising hydrolyzed hemicellulose and a second stream comprising lignin and cellulose; (b) maintaining the first liquid stream comprising hydrolyzed hemicellulose at a temperature of at least 130° C. to obtain a second liquid stream comprising furfural; and (c) separating the furfural obtained in step b) from the second liquid stream.
