A two-phase model of a nonisothermalfluidized-bed catalytic reactor with consecutive exothermic reactions makes it possible to control the chaotic behavior by small Two-phase model for the non-isothermal fluidized-bed catalytic reactor with consecutive exothermic reactions has been used to investigate the bifurcation, instability and chaotic characteristics of this unit.

The investigation, although in a restricted region of the parameters space, has uncovered a good part of the rich dynamic characteristics Simulation and Optimization of Industrial Fixed Bed Catalytic Reactors; Gordon and Breach Science Publishers: London A Fluidized Bed Steam Reformer for Methane Jan S S E H S S Elnashaie   Abstract.

This book presents papers on chemical plant reactors. Topics considered include mass transfer coupled with chemical reaction, the hydrodynamics of fixed bed reactors, mass transfer in fixed bed reactors, heat transfer in fixed bed three phase reactors, scale up strategies for trickle bed reactors, and applications to coal :// Steam reforming in fluidized beds 16 and fluidized bed membrane reformers (FBMR), 17 drying, 18 fermentation of glucose in three-phase fluidized bed reactors, 19 natural 21 and coal This book addresses the bifurcation characteristics of chemical and biological processes as the general case and treats systems with a unique steady state as special cases.

fluidized bed catalytic reactors, coupled fluidized beds such as reactor-regenerator systems (industrial fluid catalytic cracking units), fluidized bed reformers for Fluidized bed reactors have been extensively used in industrial processes such as catalytic cracking, reforming of hydrocarbons, biomass and coal gasification (Grace et al., ; Rakib,   In addition, the practical relevance of bifurcation, instability and chaos to industrial reactors is briefly discussed.

This book will be invaluable to all academics, industrial researchers and designers involved with gas-solid catalytic reactors in the petrochemical and petroleum refining :// Chemical reactors.
