摘要
在常压、573K下考察了Ni的负载量对MoOx催化剂性能的影响。当Ni的负载量不大于2%时,正庚烷的转化率随镍负载量的增加而增加;进一步增加镍负载量,对MoOx催化剂活性的促进作用减弱。镍的存在基本不影响正庚烷异构化选择性及其产物,但其裂解产物发生变化。
At 573K under atmospheric pressure, the effects of Ni loading on catalytic performance of MoOx catalyst were inwestigated. Adding of 0-2%Ni to MoO3, the catalytic activity of n-heptane increased with the increase of nickel content; Further increasing the nickel loading, increase of the activity became moderate. The isomerization selectivity and product of n-heptane didn＇t change for addition of Ni. But cracking product were affected by it.
