摘要
采用急冷方法制备了Ni-Al-Fe-Mo、Ni-Al-B、Ni-Al-Fe-B-Si、Ni-Al-Fe-Cr等多种骨架镍催化剂(统称Ni-Al-X),在磁稳定床反应器中用Ni-Al-X催化剂进行己二腈加氢制备己二胺的应用研究。在该体系中,在温度74℃、压力2.0～2.2MPa的条件下,考察了磁场强度、空速及氢油比对己二腈加氢制己二胺的转化率和选择性等的影响,利用《均匀设计与统计调优》软件对试验数据进行工艺条件设计与调优处理,在计算的优化试验条件下(磁场强度48.2kA/m、空速不大于0.5h^(-1)、氢油体积比不小于220)转化率可达98％,己二胺选择性可达66.5％。
Skeleton catalysts, such as Ni-Al-Fe-Mo, Ni-Al-Fe-B, Ni-Al-Fe-B-Si and Ni-Al-Fe-Cr (a joint name called Ni-Al-X) , were prepared by quenching. Hydrogenation of adiponitrile to hex-anediamine over Ni-Al-X catalysts was carried on a magnetic stabilized-bed reactor. The effects of mag-netic field intensity, space velocity and hydrogen to oil ratio on the conversion and selectivity were inves-tigated at 74℃ and 2. 2MPa. At the optimal test conditions obtained from simulation calculation, a magnetic field intensity of 48. 2kA/m, a space velocity less than 0. 5h-1 and hydrogen to oil ratio higher than 220, the adiponitrile conversion reached 98% with a hexanediamine selectivity of 66. 5%.
