AI Technical Summary
Existing catalysts exhibit low activity in the maleic anhydride hydrogenation process, require harsh reaction conditions, and suffer from insufficient selectivity and stability, resulting in high production costs and numerous byproducts.
The catalyst is prepared by depositing vanadium oxide, molybdenum oxide, or tungsten oxide onto the surface of a nickel-based active component and then calcining it. This process is suitable for the hydrogenation reduction reaction of maleic anhydride and succinic anhydride, improving catalytic activity and selectivity.
This method enables the efficient preparation of γ-butyrolactone under mild conditions. The catalyst exhibits high activity, good selectivity, and strong stability, reducing production costs and making it suitable for chemical production.
