Abstract
Fluidized bed reactors have unique qualities, notably temperature uniformity, favourable heat transfer and solids mobility, which make them attractive for many catalytic and noncatalytic reactions involving solid particles and a gas or liquid. However, gas fluidized bed reactors present a challenge to the engineer because their patterns of gas-solid contacting and mixing are complex and difficult to characterize. Contacting and mixing are intimately related to the hydrodynamics in the bed itself. Before discussing reactor models and simulation methods, it is essential to provide some basic understanding of some key aspects of the physical behaviour of gas-solid fluidized beds. We begin with a description of the regimes of hydrodynamic behaviour, follow with a general treatment of catalytic reaction in a two-phase, two component reactor, and then consider specific regimes and zones of fluidized beds. Models for gas-solid reactions are treated separately. A brief survey is given of some advanced models which do not fall neatly within the usual range of assumptions or conditions. Emphasis throughout is not only on what is known, but also on challenges and new developments, including the high-velocity fluidization regimes which are of increasing importance in industrial practice.
