Effectiveness Factor of Deep Oxidation of Butane, Trans-2-butene and Cis-2-butene over Pt/Al2O3 Catalyst

Abstract

Abstract: The effect of intraparticle diffusion on the deep oxidation of butane, traus-2-butene and cis-2-butene over Pt/Al₂O₃ was investigated by the flow recirculation reactor.The effectiveness factor of catalyst η was determined experimentally.The values of η are 0.42～1.27, and decrease with the rise of the reaction temperature.The pressure profile of oxygen in the pore of catalyst was calculated by Runge-Kutta method.The partial pressure of oxygen in the pore decreases with the increasing effect of intraparticle diffusion and it tends to zero at 420 ℃.

Key words: Pt/Al₂O₃, Effcctveness factor of catalyst, Butane, Trans-2-butene, cis-2-butene
