摘　　要：实验制备了系列负载型催化剂,用于双环戊二烯催化加氢合成桥式四氢双环戊二烯反应,筛选出催化性能较好的Ni/γ-Al_2O_3催化剂,并对该催化剂的处理方法、活化时间、金属负载量等因素进行了考察。结果表明,采用直接还原法,还原时间11h时制备的30%金属负载量的催化剂加氢活性较好,优化的双环戊二烯加氢反应工艺为:氢压5.0MPa,温度110℃,该条件下桥式四氢双环戊二烯收率为93%。Metal-carrying catalysts were prepared and used in the synthesis of endo-tetrahydrodicyclopentadiene from dicyclopentadiene. Ni/y-A1203 has been developed and various factors have been investigated systematically. When loading 30% （mass content） nickel as active ingredient, the optimum catalyst was prepared by direct reduction of Ni（NO3 ）2/7 Al2O3 in hydrogen for 11 h. The optimal reaction conditions are： hydrogen pressure 5.0 MPa, temperature 110℃. Under the above conditions, the yield of endo-THDCPD was 93.0%
