摘　　要：采用新型发泡非晶态Ni-P合金催化剂 ,在微型固定床连续反应器上进行了苯加氢制备环己烷的实验研究。结果表明 :这种新型发泡非晶态合金催化剂具有较好的加氢催化活性和很好的选择性 ,在体系氢压为 2 .0MPa、反应温度为 3 0 0℃ ,苯的进料速率为 3mL/h的条件下 ,环己烷的单程收率为3 3 .2 8%。试验考察了该催化剂的稳定性 ,结果表明 ,在 3 60h内 ,其催化活性没有显著变化。另外 ,该催化剂具有很好的通透性 ,催化剂层前、后几乎无压差。试验还发现 ,该催化剂没有明显的诱导期 ,无需经过预处理就有很好的加氢催化活性。因此 ,发泡非晶态Ni-P催化剂有希望成为工业催化剂。Using the novel foamed amorphous alloy-foamed Ni-P alloy-as catalyst, the hydrogenation of benzene to cyclohexane was carried out in a minisize catena fix-bed reactor. The products were analyzed by gas chromatograph. Through the experiments, the suitable processing conditions were obtained as the following: the reaction temperature 300°C, the feed rate 3 mL/h and the pressure of the system 2.0 MPa. Under these conditions, the selectivity of hexamethylene alkyl was nearly 100% and the yield was about 33.28%. The results of the research on the stability indicated that the activity didn't change much in 360 h. In addition, the catalyst has no obvious inducement time. It has a good hydrogenation activity dispense with pretreatment. So the foamed Ni-P amorphous alloy can be used as industry catalyst.
