A reaction system and method for continuously producing furan and combustible gas from biomass

Abstract

The invention belongs to the field of biomass resource utilization, and specifically discloses a reaction system and method for continuously producing furan and combustible gas from biomass, which uses cellulose and hemicellulose in lignocellulosic biomass in the first The water layer in the reaction chamber is hydrolyzed into 5-hydroxymethylfurfural and furfural, and then 5-hydroxymethylfurfural and furfural are extracted to the organic solvent layer in the first reaction chamber, then diffused into the second reaction chamber, and decomposed into furan, H 2 and CO, furan and combustible gas are obtained after two-stage condensation separation. The invention can couple the 5-hydroxymethylfurfural pathway and the furfural pathway, realize the synergistic conversion of cellulose and hemicellulose in lignocellulosic biomass to prepare furan and combustible gas, and improve the utilization rate of biomass raw materials.

Description

technical field [0001] The invention belongs to the field of biomass resource utilization, more specifically, relates to a reaction system and method for continuously producing furan and combustible gas from biomass, especially relates to a continuous conversion of lignocellulosic biomass to produce furan and combustible gas reaction system and method. Background technique [0002] Furan is a basic raw material in the field of energy and chemical industry derived from biomass. It is not only the core structure of many important pharmaceutical intermediates and optoelectronic organic materials, but also used to manufacture important industrial raw materials such as pyrrole, thiophene, benzofuran and tetrahydrofuran. Among them, tetrahydrofuran is the main raw material for the production of spandex fiber, polyurethane elastomer, etc., and the market demand is huge. However, it is mainly prepared by dehydration of 1,4-butanediol or hydrogenation of maleic anhydride in industry,...
