Intrinsic kinetics of catalytic hydrogenation of cyclopentene and styrene in pyrolysis gasoline

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.

The intrinsic kinetic experiments of catalytic hydrogenation of cyclopentene and styrene in pyrolysis gasoline over a domestic Co-Mo/A1203 catalyst were carried out in an integral micro-reactor under the following conditions： 2.4～ 4.0 MPa, 495 ～ 680 K, 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.
