CO_2气氛中T－2－4催化剂上羰基硫水解动力学研究

Study of the Kinetics of COS Hydrolysis over T-2-4 Catalyst and in CO_2 Atmosphere

本文使用内循环无梯度反应器，在５５～１６０℃，常压和二氧化碳气氛条件下，研究了Ｔ－２－４催化剂上羰基硫（ＣＯＳ）水解反应动力学。建立了如下的动力学方程．本征动力学宏观动力学确定了ＣＯＳ、ＣＯ２的反应级数分别为０．７和－１．０。

The intrinsic and macroscopic kinetic model of COS hydrolysis over T-2-4catalyst were investigated in a gradientless reactor with interal -recycle under conditions:55 ￣ 160℃, atmospheric pressure and CO2 atmosphere. Multiple regression method was used to estimate the parameters of the kinetic model of this used to estimate the parameters of the kinetic model of this system. The established intrinsic kinetic model is as foland the macroscopic kinetic model is:0. 7-order and - 1.0-order behavior were observed for COS and CO2 respectively.
