摘要：应用连续微反—色谱装置,在反应温度为210～260℃,反应压力为1.96MPa,H_2/己烷摩尔比为8的条件下,研究了己烷的五个异构体在载钯氢型丝光沸石催化剂上的临氢异构化反应动力学.结果表明,在总压和H_2/己烷摩尔比恒定条件下,已烷的异构化动力学行为可以用拟一级复杂反应网络来描述.求取了该复杂反应网络中每一步异构化反应的速率常数,各步反应的活化能在88.2～228kJ·moL^(-1)之间.
The kinetics of hydroisomerization of five hexane isomers over Pd/H - Mordenitecatalyst has been studied at a temperature rang 2 1 0 ~ 2 6 0℃ , total pressure of 1. 96 MPa and H2 /hexane mole ratio of 8 in a combination unit of catalytic pressure microreactor and gas chromatograph. The results show that this complex reaction system could be assumed to be preudomonomolecular in the case of constant total pressure and constant H2/hexane ratio. All the kinetic parameters of this reaction network have been calculated and the reaction activity energies are between 88.2~228kJ/mol.
