Title:
GAS-PHASE ALDEHYDE HYDROGENATION CATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/125060
Kind Code:
A1
Abstract:
The present application provides a gas-phase aldehyde hydrogenation catalyst, a preparation method therefor and an application thereof. The preparation method comprises the following steps: mixing an aluminum salt, a first zinc salt, a silica sol, a first precipitant and water, and performing first aging treatment to obtain a first mixed solution; mixing a copper salt, a second zinc salt, zinc powder and water, and performing ultrasonic treatment to obtain a second mixed solution; mixing the first mixed solution, the second mixed solution and a second precipitant, and performing second aging treatment to obtain a third mixed solution; adding boric acid into the third mixed solution, and performing third aging treatment to obtain a fourth mixed solution; and filtering the fourth mixed solution, and sequentially drying and roasting the obtained solid product to obtain a catalyst precursor; and mixing and molding the catalyst precursor and graphite to obtain a gas-phase aldehyde hydrogenation catalyst. The catalyst of the present application can be used for catalytically converting heavy aldehydes and improving the conversion rate of the heavy aldehydes.
