20130210089 | PROCESS FOR THE PRODUCTION OF SUGARS FROM LIGNOCELLULOSIC BIOMASS PRE-TREATED WITH A MIXTURE OF HYDRATED INORGANIC SALTS AND METALLIC SALTS - The present invention concerns a process for the conversion of lignocellulosic biomass into sugars, comprising at least three steps. The first step is a step for cooking the lignocellulosic biomass in the presence of at least one hydrated inorganic salt mixed with at least one other metallic salt. The second step is a step for separating at least one solid fraction which has undergone the cooking step, and the third step is a step for enzymatic hydrolysis of said solid fraction to convert the polysaccharides into monosaccharides. The sugars obtained thereby can then be fermented into alcohols. | 08-15-2013 |
