Effect of intraparticle diffusion on catalyst decay

The interrelation between internal diffusion and deactivation is examined. The study is centered on the copper catalyst used in the water-gas-shift reaction (WGSR). This catalyst is deactivated by the presence of chlorine in the feed. A Langmuir-Hinshelwood model for the reaction kinetics is conside...
