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. Under the conditions of reaction temperature of 210-260 ℃, reaction pressure of 1.96 MPa and molar ratio of H 2 / hexane of 8, a continuous micro-reversed-phase apparatus was used to study the effect of five isomers of hexane on the hydrogenation of palladium Hydroisomerization Kinetics of Mordenite Catalyst The results show that the isomerization kinetics of hexane can be described by a quasi-first-order complex reaction network under conditions of constant total pressure and H 2 / hexane molar ratio The rate constant of each isomerization reaction in this complex reaction network was calculated, and the activation energy of each reaction was between 88.2 and 228 kJ · mol -1.
