The main contents are as follows: A series of MCM-41-supported nickel phosphide catalysts with initial Ni/P atomic ratio of 0.5 - 2 and loading level of 10 - 40 wt % in the oxidic precursors were prepared by an in-situ reduction method. Their catalytic performances were evaluated in the HDN of quinoline.

The IR results indicate that the surface of these phosphide catalysts is partiallysulfided while the structure of the phosphides is retained under HDS reactionconditions.

CO 探针的红外光谱表明，在HDS 反应过程中，磷化物催化剂的体相结构可基本保持，但催化剂表面被部分硫化，形成了MoP_xS_y或NiP_xS_y活性相。

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。
