Research on direct conversion of xylose to furfural in high temperature water
摘要
Abstract
Direct conversion of xylose into furfural in high-temperature water（HTW） was carried out in a self-made high-pressure reactor.The effect of HTW as the reaction medium on xylose conversion and furfural yield was investigated,and was compared with others catalyst used in the literature.The effects of different solvents on the extraction of furfural were studied.The result showed that HTW was a perfect catalyst medium,which could replace liquid acid and solid acid in the conversion of xylose into furfural.The optimal furfural yield of 78% was obtained at a reaction temperature of 200 ℃,a holding time of 3 h and initial xylose concentration of 10%.In addition,furfural could be well extracted by n-butyl acetate.Therefore,a novel approach to furfural production is presented,providing a basis as well as technical parameters for its commercialization.关键词
