LV13676B - Method for combined producing furfural and ethanol - Google Patents

Abstract

This invention relates to industrial production of furfural and ethanol from pentosan-containing plant sources: from broad-leaved wood, corncobs, straw, bagasse and the like. The raw material is shred till the particle size like that of technological chips, it is mixed with catalyst solution and treated in a current of saturated dry steam at super-atmospheric pressure. The steam coming out of reactor is condensed, and furfural is separated by rectification. Residual cellulose is hydrolyzed to glucose by fermentation, and after addition prescribed amount of required salts the obtained glucose is fermented to ethanol.

Method for the total production of furfural and ethanol 1. A process for the total production of furfural and ethanol from plant material containing pentosan by converting pentanes into furfural followed by hydrolysis of residual cellulose remaining in the residue of the raw material to glucose and digestion of glucose to ethanol, characterized in that conversion of pentosan to furfural occurs in the presence of a catalyst solution taken at a concentration of not less than 10% of the saturated concentration of this solution and in an amount of up to 20% by weight of the dry starting material and of the lignocellulose residue remaining in the hydrolysis to the glucose with glucose with enzymes. Method according to claim 1, characterized in that the pentosans for the furfural conversion process are used as catalyst solutions of mineral acid or mineral acid and / or salts thereof, which dissociate cations with a charge of not less than two and the process takes place under pressure 0 , 2 - 0.9 MPa.
