摘要: 用玻璃外循环无梯度反应器研究在Pt/Al2O3催化剂上丁烷、反-2-丁烯及顺-2-丁烯深度氧化的内扩散影响.测出催化剂有效因子η为0.42~1.27,并随反应温度升高而下降.用Runge-Kutta法计算氧在催化剂孔内压力分布,孔中心氧分压y0随内扩散影响加大而下降,在420℃y0如趋于零.

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 ℃.
