Abstract

The invention belongs to the technical field of furfuryl alcohol preparation, and discloses a method for preparing furfuryl alcohol by catalyzing transfer hydrogenation of furfural through non-noble metal-loaded nitrogen-doped carbon. According to the method, a cobalt oxide-loaded nitrogen-doped carbon catalyst is used for catalyzing furfural to prepare furfuryl alcohol, wherein nitrogen-doped carbon in the catalyst is a carrier, and cobalt oxide in the catalyst is an active component. According to the method, a nitrogen-doped carbon material loaded by cobalt oxide is used as the catalyst, organic alcohol is used as a solvent and a hydrogen donor, and transfer hydrodeoxygenation of furfural is catalyzed to synthesize furfuryl alcohol; the method is simple in the whole process, easy to operate and low in cost; a reaction system is green; the catalyst is high in activity; the furfuryl alcohol is high in selectivity and yield; and the method has wide industrial application prospects. H2 is prevented from being directly used, and the organic alcohol serves as the hydrogen donor, so storage and use are convenient, the requirement of a reaction solvent on hydrogen solubility is lowered,and hydrogenation effect is good.

Description

technical field [0001] The invention belongs to the technical field of furfuryl alcohol preparation, and in particular relates to a method for preparing furfuryl alcohol through the transfer hydrogenation of furfural catalyzed by nitrogen-doped carbon supported by non-noble metals. Background technique [0002] In recent years, due to the massive consumption of fossil fuels and natural resources, the demand for the development of clean and efficient energy materials to replace traditional fossil fuels has become more and more urgent. It is urgent to find a renewable, clean and rich energy material. As the only renewable carbon, biomass has broad application prospects in solving the energy crisis and environmental pollution problems in today's increasingly severe energy crisis and environmental pollution problems. The furfural formed by the dehydration of biomass sugar cracking can be hydrogenated and reduced to furfuryl alcohol under the condition of catalyst, because furfur...
