通过处理等温积分反应器的试验数据，研究了馏分油催化脱蜡一级串联失活反应动力学模型。对动力学方程式的参数进行了估值，进而确立了在 Ｐｄ／ Ｚｎ Ｈ Ｚ Ｓ Ｍ ５ 催化剂上馏分油催化脱蜡的失活动力学方程。讨论了 Ｈ Ｚ Ｓ Ｍ５ 沸石催化剂浸渍金属 Ｎｉ或 Ｐｄ／ Ｚｎ 和高温水蒸气处理对催化剂失活速率及选择性的影响。 By processing the experimental data of the isothermal integration reactor, the kinetic model of the catalytic dewaxing first-order in-line inactivation reaction was studied. The parameters of kinetic equation were estimated, and then the kinetic equations of deactivation for catalytic dewaxing of distillate oil on Pd / ZnHSM5 catalyst were established. The effect of HZ S M5 zeolite catalyst impregnated with metal Ni or Pd / Zn and high temperature steam treatment on the catalyst deactivation rate and selectivity was discussed.
