PREDICTIVE MODELING OF RISER AND DOWNER CIRCULATING FLUIDIZED BEDS: APPLICATION TO FLUID CATALYTIC CRACKING

摘要

Two models, describing the hydrodynamics of Circulating Fluidized Bed (CFB) riser and downer reactors, are integrated with a FCC reaction model. The simulation compares the performance of the two reactor configurations and the results illustrate some of the beneficial features of downer reactors.
