EFFECT OF INTRAPARTICLE DIFFUSION ON CATALYST POISONING
The interrelation between internal diffusion and deactivation is examined. The study is centered on the Ni/Al2O3 catalyst used in the benzene hydrogenation. The catalyst is deactivated by the presence of thiophene in the feed. A Langmuir-Hinshelwood and power-law model for the reaction kinetic is considered. The life of the catalyst pellet increases when diffusional resistance for the poison increases. A general equation for the effectiveness factor which includes the catalyst decay is defined.
