The process of transient diffusion, adsorption and heterogeneous reaction in porous catalysts is analysed using the method of volume averaging. The analysis illustrates under what circumstances the effective diffusivity tensor is independent of the adsorption and reaction process, and thus indicates
A population balance model has been developed for catalyst propemes, which IS m good agreement with commercml flmd crackmg data The apphcatlon of Markov theorv gives a detaded account of the volume, age, actlvlty, and residence time of catalvsts for each oartlcle size class This model has been used
## Abstract Fluid catalytic cracking (FCC) is the primary conversion process in oil refining. The performance of an FCC riser strongly depends on the interactions between oil/catalyst flow and cracking kinetics, but most FCC riser models do not consider such interactions. Accordingly, this work dev
