摘要
在自行设计和安装的一套微反 色谱联用装置上,以TGH为催化剂,进行了二氧化碳对羰基硫催化水解本征动力学影响的研究,得出了在低温50℃~70℃、高水汽摩尔比(H2O COS=60~550),分别对原料气中有无存在CO2的条件下,采用非线性Marquart法对实验数据进行回归,所建立的本征动力学方程式为:1.82×1014exp-75800H2O8.374T×PCOS×P-0.
A microreactorGC apparatus has been used for studying COS hydrolysis reaction kinetics over TGH catalyst The intrinsic reaction kinetics of COS hydrolysis over a TGH catalyst was investigated in the temperature range of 50?℃~70?℃、 H2O/COS molar ratio of 60~550 with the presence of CO2 Nonlinear Marquart Regression was employed to analyze the experimental data The reaction kinetics are expressed as follows:-rCOS=dxdWFCOS=1.82×1014exp-75?8008.374T×PCOS×P-0.5H2O1+kCO2×PCO2The kinetic model can be interpreted the reaction in terms of mechanism The presence of CO2 seems not to change rate constant and activation energy of COS hydrolysis reaction
