摘要：

Intrinsic rates of benzene hydrogenation have been measured on a commercial Ni/kieselguhr catalyst. The rates have been correlated according to the power law, rB = k-pH2 O 32-pB°′21, and also according to the model rB = [WKVpB/(1 + KB-pB)] [Ph/(PH2 + PB)L which postulates reaction between hydrogen gas and adsorbed benzene molecules. The apparatus was an isothermal, tubular, differential reactor. Temperature was varied from 67 to 90 °C, hydrogen partial pressure between 1000 and 3000 torr, and benzene partial pressure from 70 to 286 torr. Specific reaction rates k and adsorption parameters KB have been correlated by the Arrhenius law. © 1979, American Chemical Society. All rights reserved.
