Co-production method of microcrystalline cellulose and polyol in terms of cellulose hydrolysis and lignocellulose liquefaction

摘要

The present invention relates to a process for producing a cellulose acylate, which comprises lignin and hemicellulose removed from lignocellulosic biomass (A), acid hydrolysis of cellulose produced in the pulp manufacturing process (A) to produce MCC (A) ) Instead of discharging the residue (A) produced in the pulp manufacturing process (A) to industrial waste, lignin and hemicellulose removed in the pulp manufacturing process (A) are circulated to the lignocellulosic biomass (B) (B) from the lignocellulosic biomass (B), and the liquefied biomass is filtered to separate the polyol (B), and the resulting residue (B) MCC (B) is separated from the polyol (B) produced by circulating the raw material lignocellulosic biomass (A), and acid hydrolysis of cellulose produced in the pulp manufacturing process (A) (B) in the biomass liquefaction process (B) Minimize industrial waste in the manufacturing process, and that relates to the efficient co-produced by the polyol and the MCC.
