Title:
METHOD FOR PREPARING 2-METHYLTETRAHYDROFURAN BY USING WASTE BIOMASS
Document Type and Number:
WIPO Patent Application WO/2023/193425
Kind Code:
A1
Abstract:
The present invention provides a method for preparing 2-methyltetrahydrofuran by using waste biomass and belongs to the technical field of chemical production. In preparation of 2-methyltetrahydrofuran in the present invention, a catalyst is used to perform catalytic hydrogenation on furfural to obtain 2-methyltetrahydrofuran. In a preparation process, a Cu-Ni bimetallic catalyst is used in cooperation with phenylhydrazine hydrochloride and sodium vanadate to serve as a hydrogenation reaction catalyst, and, by using the catalyst, a hydrogenation reaction can be carried out under a relatively low pressure and has a low requirement for a reaction apparatus, thus facilitating large-scale preparation. In addition, the activity of the catalyst is effectively improved by the addition of the phenylhydrazine hydrochloride and the sodium vanadate, making a furfural conversion ratio close to 100%.
