Title:
RUTHENIUM-NICKEL/ACTIVATED CARBON CO-SUPPORTED CATALYST, PREPARATION THEREOF AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/114287
Kind Code:
A1
Abstract:
The present invention relates to a ruthenium-nickel/activated carbon co-supported catalyst, a preparation method therefor and a use thereof in the preparation of sugar alcohols by means of sugar catalysis and hydrogenation. According to the present invention, ruthenium and nickel metals are co-loaded, by means of a simple impregnation and reduction method, on activated carbon with a high adsorption speed and a large specific surface area, to prepare an Ru-Ni/AC catalyst, which is used to prepare sugar alcohols, such as xylitol, arabitol, sorbitol, mannose, and maltitol. The catalyst is highly active and stable, can be reused in multiple batches, and has a high product yield. In summary, the catalyst of the present invention has a simple preparation process, a low production cost, a high catalytic efficiency and a good stability, is suitable for the preparation processes of various sugar alcohols, and has a good universality.
