为考察H_2/C_2H_2可变条件下乙炔加氢的串行反应动力学行为,利用Langmuir-Hinshelwood机理模型关联稳态实验数据而进行动力学模型鉴别。结果表明,反应是按表面控制的机理进行的。据此求出了乙炔、乙烯的加氢反应速率常数和吸附参数。
In order to investigate the kinetics of serial reaction of hydrogenation of acetylene under variable H_2 / C_2H_2 conditions, the kinetic model was identified by using the Langmuir-Hinshelwood mechanism to correlate steady-state experimental data. The results show that the reaction is based on the surface-controlled mechanism. Based on this, the hydrogenation rate constants and adsorption parameters of acetylene and ethylene were obtained.
