摘　　要：本文以活性助剂的可溶性盐与特种载体采用浸渍沉淀法制备了用于1,4-丁二醇二段加氢催化剂,在120℃、液时空速1.5h-1、氢气流量3 000mL/min、反应压力16MPa条件下,可将1,4-丁二醇粗液全部转化,1,4-丁二醇选择性可达到95%以上,能够满足工业生产的要求。A second section of hydrogenation catalyst which is used for the reppe two-steps synthesis of 1,4-butanediol has passed performance test.The preparation method is impregnation precipitation method by soluble salts of active additives with specialty carrier through.In this process,feed liquid can downright converse,and selectivity of 1,4-butanediol can reach to 95% at least under the conditions of reaction temperature at 120℃,LHSV at 1.5h^-1,the flow of hydrogen at 3 000mL/min,reaction press at 1MPa.
