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。

In the dynamic experiment of wet air oxidation of phenol with pelletized Ru/ZrO2-CeO2, phenol and COD reduction was maintained at 96% during 110 h of reaction. The concentration of the main intermediates was small. In the experiment of catalytic wet air oxidation of phenol, the leaching concentration of active species was small. There were small amounts of carbonaceous deposits on the surface of the used catalysts, and the carbonaceous deposits can be completely oxidized at 300℃.

在110h的催化湿式氧化苯酚反应中，苯酚和COD的去除率维持在96%左右，反应过程中活性组分的溶出浓度很小，催化剂表面有少量的积炭，但积炭在300℃能够被完全氧化。
