The effect of MCM-41 modification by K~+ and the introduction of HY on the HDN performance of the supported nickel phosphides were investigated. The modification of K~+ on MCM-41 hardly affected its activity in quinoline HDN.

考察了MCM-41改性后负载磷化镍催化剂及在磷化镍催化剂中加入第二组分后HDN反应性能。

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用，喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上，阻碍了反应物分子的吸附，从而对喹啉的HDN反应有强烈的抑制作用。
