Abstract

Kinetic studies of hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) reactions were performed. The hydrogenating activity of the synthesized Ni₆PMo_nW_(12–n)/Al₂O₃ catalysts was compared with that of the commercial reference catalyst in the process of hydrotreating of heavy mixed oil feedstock. It was shown that the HDS reaction is described by a pseudosecond order equation, and HDN, by a pseudofirst order equation. The obtained hydrogenates meet the requirements to the quality of feedstock for catalytic cracking plants in terms of coking capacity and sulfur and nitrogen contents.

摘要

进行了加氢脱硫 (HDS) 和加氢脱氮 (HDN) 反应的动力学研究。将合成的 Ni ₆ PMo _n W _{(12– n )} /Al ₂ O ₃催化剂的加氢活性与商业参考催化剂在重质混合油原料加氢处理过程中的加氢活性进行了比较。结果表明，HDS 反应由伪二阶方程描述，HDN 反应由伪一阶方程描述。所得氢化物的焦化能力和硫、氮含量均满足催化裂化装置原料质量要求。
