摘要：应用微型催化反应－色谱装置，在总压１～２ＭＰａ、温度４７３～５７３Ｋ、氢油体积比５００、质量空速１～３０ｈ￣（－１）的范围内，研究了噻吩在Ｍｏ－Ｎｉ－Ｃｏ／Ａｌ_２Ｏ_３催化剂上的加氢脱硫动力学。根据加氢脱硫反应具有极限转化率的特点；用类二级反应的数学模型描述噻吩脱硫的动力学行为，求得活化能为７６．２１ｋＪ／ｍｏｌ，频率因子为３．６７×１０８。
The kinetics of thiophene hydrodesulfurization over a commercial Mo-Ni-Co/ Al_2O_3 catalyst in a temperature range 473～573K,total pressure 1～2MPa,and volume ratio of hydrogen to hydrocarbon 500 was studied in a continuous-flow microreactor.Experiment data showed that the hydrogenolysis of thiophene has a maximum conversion yield which is close to one.A pseudo-second order reaction model was used to describe the kinetic behavior of thiophene hydrodesulfurization and the kinetic parameters of this model were given.
