A method for catalytically converting 2-methylfuran into 1,4-pentanediol selectively

Abstract

The invention provides a method for catalyzing the selective conversion of 2-methylfuran into 1,4-pentanediol. In this application, 2-methylfuran is used as raw material, and a supported platinum-based bimetallic catalyst is used to catalyze the hydrogenation conversion of 2-methylfuran, in which PtNi 5 / MWNT catalyst, at 2MPa H 2 and 120°C, in ethanol / H 2 One-pot hydrogenation of 2-methylfuran in O (volume ratio=1.5:2.0) solvent, the conversion rate of 2-methylfuran is 98%, and the productive rate of 1,4-pentanediol is 69%, which is excellent Most of the catalysts reported so far. The preparation process of the present invention is simple, without adding acid and alkaline additives, the raw materials can be regenerated, the catalyst has high activity and stability, the reaction conditions are milder, the energy consumption is reduced to a certain extent, the environment is more friendly, and it can partially relieve the current Energy problems facing the world. Therefore, the present invention has broad application potential in industrial production.

Description

A kind of method that catalysis 2-methylfuran is selectively converted into 1,4-pentanediol technical field The invention belongs to the field of biomass energy catalysis, and relates to a kind of catalytic biomass derivative 2-methylfuran hydrogenation to produce A method for preparing fine chemical 1,4-pentanediol, in particular to a multi-active component catalyst, which can effectively catalyze Selective hydrogenolysis of 2-methylfuran to prepare 1,4-pentanediol. Background technique In the energy and chemical industries, fossil carbon sources are increasingly being replaced by renewable carbonaceous materials to reduce temperature [0002] emissions of the greenhouse gas carbon dioxide, thereby slowing global warming. Lignocellulosic biomass is an abundant and renewable carbon resource It is expected to replace traditional non-renewable fossil resources in chemical and fuel production. Lignin, Cellulose and Hemicellulose Derived from lignocellulosic biomass, t...
