氧化铝基硫回收催化剂反应动力学研究
|
摘要
针对LS-02催化剂进行反应动力学研究,通过不同硫化物在催化剂上的升(降)温表面反应,改变硫化物浓度得到不同温度和反应物浓度下的反应结果,并建立相应的速率方程,由速率方程得出催化剂上的具体反应形式及过程。结果显示:回归值与实验值偏差很小,残差期望值接近于0,说明所建立的动力学模型是有效的。
The reaction kinetics of LS-02 catalyst is studied.The reaction results of different temperatures and reactant concentrations are obtained by changing the sulfide concentration by the surface reaction of different sulfides on the catalyst.The corresponding rate equation is established.The specific reaction form and process on the catalyst is derived from the rate equation.The results show that the regression value has little deviation from the experimental value, and the residual expected value is close to 0, indicating that the established kinetic model is effective.
