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。
