Mathematical modeling of fluidized bed reactors. In the past fluidized bed reactor modeling has focused on heterogeneously catalyzed gas‐phase reactions. Recently, however, greatly increased activity is obvious in the field of fluidized bed combustion where attempts are made to describe coal combustion in the fluidized bed and emission of sulphur dioxide and nitric oxides from FBC units, with the ultimate aim of modeling the operating behavior of industrial fluidized bed combustors. The present paper surveys the state of the art in fluid bed reactor modeling. The influence of the fluid‐dynamic state of fluidization which is governed by gas and solids properties, fluidizing velocity, and bed geometry, as well as the influence of different zones within the reactor and of design details, respectively, are discussed on the basis of several models described in the literature.
