在215—260℃、临氢总压为1.96MPa、H_2/C_6摩尔比为8的反应条件下研究了己烷五个异构体在M-1型催化剂上临氢异构化反应的动力学。研究结果表明,在总压和H_3/C_(?)摩尔比恒定的条件下,己烷临氢异构化反应的动力学行为可以用拟一级反应网络模型来描述。作者应用“等时间法”求取了该复杂反应网络中的各步反应速度常数和活化能。 The kinetics of hydroisomerization of five isomers of hexane on M-1 catalyst was studied under the reaction conditions of 215-260 ℃, total hydrogen pressure of 1.96 MPa and H 2 / C 6 molar ratio of 8 . The results show that the kinetic behavior of hydroisomerization of hexane can be described by the pseudo first-order reaction network model under the conditions of constant total pressure and molar ratio of H_3 / C_ (?). Using the “equal time method”, the authors obtained the reaction rate constants and activation energies of each step in the complex reaction network.
