用拉普拉斯变换等数学处理方法,由连续方程推导出了反应组分皆为弱吸附时。在脉冲催化反应的真实条件下,反应组分的吸附系数表达式。并用该理论系统地考察了在实际反应条件下,环己烷在Pt-Al_2O_3上脱氢中环己烷、苯和氢的吸附系数,求得了相应的吸附热。同时还由脉冲反应的表观速度常数和所求得的环己烷吸附系数进一步求得了表面反应动力学参数。此外,对氢、环己烷和苯的吸附态物种进行了讨论,认为不同的吸附态物种是被吸附在催化剂表面上的不同类的活性中心上。
Using Laplace transform and other mathematical methods, the continuous equations derived from the reaction components are weakly adsorbed. Under the real conditions of the pulse catalytic reaction, the adsorption component of the reaction component is expressed. The adsorption coefficient of cyclohexane, benzene and hydrogen in the dehydrogenation of cyclohexane on Pt-Al 2 O 3 was systematically investigated by using this theory, and the corresponding heat of adsorption was obtained. At the same time, the surface reaction kinetics parameters were further obtained from the apparent velocity constants of the pulse reaction and the obtained cyclohexane adsorption coefficient. In addition, adsorbed species of hydrogen, cyclohexane and benzene are discussed, suggesting that different adsorbed species are adsorbed on different types of active sites on the surface of the catalyst.
