摘要

以工业两段绝热床中运行近4000h的结炭B—02催化剂为研究对象

利用内循环无梯度反应器

求得催化剂烧炭再生本征动力学模型.由于催化剂中的结炭是多核芳烃

因此可简单地以碳氧化和氢氧化的动力学方程表征烧炭再生动力学模型.碳氧化动力学方程为-dN_c/N_Cdt=K_Cp_(O_2)~(0.3)(N_C/N_C)~1.3式中

一段催化剂 K_C=13.37exp[-78.97×10~3/(RT)]二段催化剂 K_C=96.54exp[-89.30×10~3/(RT)]氢氧化动力学方程为-dN_H/N_Hdt=K_H(N_H/N_H)~1.1式中

一段催化剂 K_H=0.48exp[-39.04×10~3/(RT)]二段催化剂 K_H=4.79exp[-52.03×10~3/(RT)]

Abstract

This paper deals mainly with the regeneration of coked B-02 catalyst which has been run in the two stage industrial adiabatic beds for nearly 4000 hours. Experiments were carried out in an internal recycle gradientless reactor. The intrinsic kinetic model for burning regeneration of the coked catalyst was obtained by using non-linear least-square method. The kinetic model can be expressed simply in terms of the oxidation of carbon and hydrogen because the coke

in fact

is polynuclear aromatics composed of carbon and hydrogen. The kinetic equations for carbon oxidation For the first adiabatic bed catalyst For the second adiabatic bed catalyst The kinetic equations for hydrogen oxidation For the first adiabatic bed catalyst For the second adiabatic bed catalyst
