Abstract

The invention discloses a method for preparing dimethylfuran through electrocatalytic hydrogenation of 5-hydroxymethylfurfural in a proton exchange membrane reactor. According to the method, a protonexchange membrane (PEM) electrolytic tank is adopted as the reactor for carrying out catalytic hydrogenation on HMF to form DMF, protons, electrons and oxygen are generated in anode electrolysis water, and the protons reach a cathode through a PEM; and in the cathode, the HMF is electrochemically reduced into the DMF by being combined with the protons generated from the anode electrolysis water. The method can be carried out under the conditions of the room temperature and barometric pressure and the condition of being free of outside hydrogen supply. Compared with a traditional DMF preparation method, the method is low in energy consumption and cost and high in productivity and has high practicality and good industrialization prospects.

Description

Technical field [0001] The invention belongs to the field of biomass catalytic conversion and chemical engineering, and specifically relates to a method for preparing dimethylfuran by electrocatalytic hydrogenation of 5-hydroxymethyl furfural in a proton exchange membrane reactor. The invention can achieve low energy consumption and low energy consumption. High-yield preparation of dimethyl furan is achieved under the condition of cost. Background technique [0002] With the massive consumption of fossil energy by human society, the development of new renewable alternative energy sources has become a top priority. As a product of biophotosynthesis, biomass has the characteristics of a wide range of sources, low price, and environmental protection, and has received widespread attention. 5-Hydroxymethylfurfural (HMF) is a very valuable lignocellulosic biomass derivative. Its hydrogenolysis product, dimethylfuran (DMF), is an excellent biomass fuel with higher energy density than e...
