采用现代测试技术对糠醛气相加氢铜铬催化剂(简称BHK型催化剂)进行综合分析,对催化活性组分提出新见解。根据加氢小试结果,讨论铬铜原子比对催化剂活性、选择性及负荷能力的影响,提出了适宜铬铜原子比及相应的加氢条件。 Modern testing techniques were used to synthesize furfural gas-phase copper-chromium catalyst (BHK-type catalyst), and put forward some new opinions on the catalytically active components. According to the result of hydrogenation test, the effects of atomic ratio of chromium and copper on the activity, selectivity and loading capacity of the catalyst were discussed. The suitable atomic ratio of chromium to copper and the corresponding hydrogenation conditions were proposed.
