Catalyst decay by simultaneous sintering and poisoning: effects of intraparticle and interfacial gradients
The influence of internal and interfacial diffusion on catalyst deactivation by simultaneous sintering and poisoning is examined. The study focuses on the copper catalyst used in the water gas shift reaction (WGSR). It is found that catalyst life increases when internal and external poison diffusion...
