摘要：

The present manuscript offers new insights into the fundamental mechanisms of catalytic cracking. Adsorption and diffusion are studied under reaction conditions similar to those of fluid catalytic cracking (FCC); an approach advancing the study of adsorption and diffusion of reactants on zeolitic catalysts. This method surpasses traditional studies done at low temperatures under low or no reactivity conditions. Experiments are performed in a novel fluidized CREC riser simulator using FCC catalysts of various crystallite sizes. Different catalyst operating regimes are observed under simultaneous chemical species adsorption, reaction, and diffusion. (C) 2004 Elsevier Ltd. All rights reserved.
