Abstract
The invention discloses a Cu/SiO2 catalyst. A preparation method for the Cu/SiO2 catalyst comprises: by taking SiO2 as a carrier, loading an active component copper, wherein the loading capacity of copper is 10-40wt%; preparing a copper ammine solution through precusor salt of copper and ammonia water; then adding polyethylene glycol; then adding the SiO2 carrier, stirring, drying, roasting and reducing the mixture to prepare the Cu/SiO2 catalyst with high dispersity and high activity; and catalyzing dimethyl maleate for one-step hydrogenation to efficiently synthesizing tetrahydrofuran by using the Cu/SiO2 catalyst. The Cu/SiO2 catalyst disclosed by the invention has the advantages of being high in raw material conversion rate and good in target product selectivity.
