Summary:The present invention relates to a method for separating a lignocellulosic raw material by an improved formic-acid-pretreated lignocellulosic biomass, according to the method, an oxidizing agent is added into a formic-acid solution to significantly improve the selectivity of pretreatment separation of cellulose, hemicellulose and lignin, and the recovery rate of the three components of the cellulose, hemicellulose and lignin can be increased.
