APPARATUS AND METHOD FOR CHEMICALLY PRETREATING HERBACEOUS BIOMASS BY USING HIGH-CONCENTRATION ORGANOSOLV

摘要

The present invention relates to a biomass pretreatment apparatus using a high-concentration organosolv catalyst, and a method for treating biomass by using same, and to a treatment method used in the recovery and reuse of a catalyst to be used for carrying out chemical treatment, and minimizes the generation of by-products by reacting biomass by means of an organosolv catalyst, and induces the maximum recovery of a pretreated solid part and, simultaneously, uses, as a pretreatment catalyst, a high-concentration organosolv catalyst, having an extremely low water amount, for enabling a used solvent to be recovered and reused.
