大庆减压蜡油在提升管催化裂化试验装置中表观动力学的研究

STUDY ON APPARENT KINETICS OF CATALYTIC CRACKING OF DAQING GAS OIL IN A LABORATORY UNIT

本文通过小型催化裂化试验装置研究了大庆减压蜡油在Y-15分子筛催化剂上催化裂化的表观动力学。用佛罗斯特公式处理试验数据的结果表明,在提升管反虚装置中大庆减压蜡油的裂解反应是一级自阻反应。由实测得的反应级数、活化能以及自阻系数等动力学参数均与文献值相同。

The apparent kinetics of catalytic cracking of Daqing vacuum gas oil(VGO) on Y-15 zeolite catalyst was investigated with a laboratory catalytic cracking unit.The data were treated with Frost equation.The results showed that the cracking reaction of Daqing VGO is a first order self-resistive reaction. The reaction order,activation energy and coefficient of selfresistive reaction thus obtained are identical with those in literatures.
