Continuous packed bed reactors are the most widely used reactors for immobilized enzymes and immobilized microbial cells. In these systems, it is necessary to consider the pressure drop across the packed bed or column, and the effect of the column dimensions on the reaction rate. Click on Back to return to Types of Reactors. One of the most common reactors in the chemical industry, for use in heterogeneous catalytic processes, is the packed bed reactor. This type of reactor is used both in synthesis as well as in effluent treatment and catalytic combustion.
Originally, fixed-bed reactors were the only commercially viable reactor type due to technological limitations. However, they also presented drawbacks mainly in the constraints existing in access to the catalyst material. Figure 1: Randomly dumped packing material used in packed beds. Columns used in certain types of chromatography consisting of a tube filled with packing material are called packed columns and their structure has similarities to packed beds. Application of a Eulerian-Eulerian approach to modeling flow in fixed bed as well as trickle bed reactors is discussed. A methodology of applying computational flow modeling to enhance the performance of a radial flow fixed bed reactor is discussed with the help of an example.

Arguments are provided to show that the application of hyperbolic-type equations improves the description of dispersion in packed-bed reactors. Introduction.
