摘要

Improvements in the process of acid hydrolysis of lignocellulosic material and in a fast reactor for hydrolysis, said lignocellulosic material being fed in different levels of a reactor (10) and contacted with the flows of organic solvent of lignin, water and a solution extremely. Uu00edda of an acid inogu00e2rnico strong.In order to obtain a liquid phase hydrolysis extract and a solid phase material not reacted and undissolved. A controlled flow of steam is injected into the different levels of the reactor, so as to provide appropriate temperatures of organic solvent and strong inorganic acid and forming the desired products (sugars). A flow of the liquid phase is recirculated in the different levels of the reactor.The remainder of the liquid phase is withdrawn from the reactor, cooled off and subjected to solvent evaporation to obtain a concentrate of the reaction products, and the lignin transferred by decantation and the concentrate transferred the procedural steps that follow.
