ADVANCES IN MODELING OF FLUIDIZED-BED CATALYTIC REACTORS: A COMPREHENSIVE REVIEW

A number of fluidized-bed catalytic reactor models have been proposed during the past half-century based on conservation equations as well as empirical relations. This article presents a comprehensive review of these models, ranging from the classic and pioneering reactor models found in the literature to the current state-of-the-art. Each model incorporates a different set of assumptions, leading to different expressions for simulating reactor performance. Forty models are analyzed depending on the characteristics of their conservation equations and their underlying assumptions by reducing each model to a sequential combination of assumptions. This review contributes to the elucidation process for choosing the appropriate model to simulate a specific fluidized-bed reactor.
