摘    要:采用微型等温积分反应器,在2.4~4.0MPa、495~680K、氢与裂解汽油摩尔比2.0~3.6和裂解汽油中环戊烯和苯乙烯质量分数分别为1.7%~4.0%和0.7%~4.0%的条件下,对国产Co-Mo/Al2O3催化剂上环戊烯和苯乙烯催化加氢的本征反应特性进行了实验研究。以Complex优化法和Merson迭代法对动力学实验数据进行非线性参数估值,建立了能良好吻合实验数据的、裂解汽油中环戊烯和苯乙烯催化加氢的幂函数型本征动力学模型。

Abstract:The intrinsic kinetic experiments of catalytic hydrogenation of cyclopentene and styrene in pyrolysis gasoline over a domestic Co-Mo/Al2O3 catalyst were carried out in an integral micro-reactor under the following conditions: 2.4~4.0MPa, 495~680K, H2/pyrolysis-gasoline molar ratio 1.8~3.5, and the mass concentration of cyclopentene and styrene in feed pyrolysis-gasoline, 1.7%~4.0% and 0.7%~4.0%, respectively. By means of the complex optimal method and Merson integral method, power-law type intrinsic kinetic models of catalytic hydrogenation of cyclopentene and styrene were developed, and a good agreement between the experimental and calculated data by the kinetic models estimated here was obtained. 
Keywords:catalytic hydrogenation   kinetics   pyrolysis gasoline    cyclopentene   styrene
