PROCESS FOR THE CONTINUOUS HYDROLYSIS OF CELLULOSIC BIOMASS AND ITS USE AND PROCESS FOR THE PRODUCTION OF MONOSACARIDES, SUGAR CHEMICALS, OR MATERIALS ALONG WITH SULFONED LIGNIN

摘要

process for the continuous hydrolysis of cellulosic biomass and process for the production of monosaccharides, sugar-based chemicals, biofuels or materials together with sulfonated alignine of lingnocellulosic biomass. The present invention relates to a continuous process for enzymatic hydrolysis of cellulosic biomass and an apparatus for carrying out such process. According to the present invention, a steady state is reached in a reactor with respect to the hydrolysis reaction. in this sense, the total high solids cellulosic biomass (preferably 10% or greater, even more preferably between 15 and 30%) is continuously added to said reactor, while at least partially hydrolyzed cellulosic biomass is continuously removed from said reactor. reactor. the steady state is adjusted, ie the amount of cellulosic biomass added and the amount of at least partially hydrolyzed cellulosic biomass removed are adjusted so that the retention time of a portion of the cellulosic biomass added in the reactor is longer than than its "liquefaction time", ie the time required to transform a solid suspension to the time required to transform a solid suspension into pumpable liquid during hydrolysis, ie the time required to reduce the viscosity of the solid. mud to a value that is acceptable for further processing.
