Abstract

Experimental evidence is presented to support two key aspects of a conceptual model for explaining enhanced hydrocarbon cracking activity of steamed vs. unsteamed Y zeolites. First, it is shown how the cracking mechanism shifts with changing concentrations of adsorbed olefins. Second, evidence is presented to support the suggestion that diffusion of olefins inside the zeolite may influence the observed reaction rate at low temperatures.
