Development of maleic anhydride hydrogenation catalysts

2026-01-27View Original

Thread Content

Cyclohexanone oxide hydrogenation catalysts are used in the production of succinic anhydride, γ-butyrolactone, 1,4-butanediol, furan, and others. Among them, precious metal catalysts include Pd/Ru/Re/Au, etc., while non-precious metal catalysts are mainly Cu and Ni-based catalysts. The lowest reaction conditions known so far are a hydrogen pressure of 4 MPa and a temperature of 190°C, under which BDO with a selectivity of over 90% can be produced. Could you share the type of catalysts used in your current production process as well as the reaction conditions?
