近年发展起来的新的动态技术能够用于分离测定非均相催化反应的吸附平衡,吸附和表面反应速率系数,而中毒实验使人们能够测定催化剂表面上活性位的容量和强度性质。如果把两者结合起来(可称作动态中毒法)就有可能研究催化剂表面上活性位性质与其动力学参数间的关系。本文的目的,是要在作者早先工作的基础上,在三相浆态床反应器中,应用动态中毒法探索研究Pd/Al_2O_3催化剂表面上活性位性质及其与α-甲基苯乙烯
New dynamic technologies developed in recent years can be used to separate the adsorption equilibrium, adsorption and surface reaction rate coefficients of heterogeneous catalytic reactions, and poisoning experiments allow one to determine the capacity and strength properties of the active sites on the catalyst surface. By combining the two (known as kinetic poisoning) it is possible to study the relationship between the active site properties on the catalyst surface and its kinetic parameters. The purpose of this paper is to explore the active sites on the surface of Pd / Al 2 O 3 catalyst and its interaction with α-methylstyrene in the three-phase slurry state reactor based on the previous work of the author.
