Table 4.4 Comparison of typical properties of catalytic and gas-solid fluidized-bed reactors.

Practically all industrial gas-solid fluidized bed reactors operate at temperatures well above ambient, and some, such as those used in the production of polyolefins, also operate at elevated pressures. It is therefore important to know how fluidized beds behave under high temperatures and/or pressures and if possible to predict this behavior from observations made under ambient conditions. The emphasis here will be on those aspects of the subject that are of direct relevance to the design and operation of fluidized bed plant a comprehensive review of the more academic aspects can be found in the review by Yates (1996). 

The first attempt at modeling gas-solids fluidized bed reactors employed ideal or simple one-parameter models, i.e., plug flow, eomplete-mixed, dispersion,...
