Columns are widely used as packed-bed or fixed-bed reactors in the chemical process industry. Packed columns are also used for carrying out chemical separation techniques such as adsorption, distillation, extraction and chromatography. A combination of the variability in flow path lengths, and the variability of velocity along these flow paths results in significant broadening in solute .

Downloadable (with restrictions)! In this paper, we propose to study the dynamics of fixed bed reactors with axial dispersion in the general case of a non-isothermal process involving N components and M reactions. It will be shown by using singular perturbation that for large dispersion coefficient values, the fixed bed reactor tends to a stirred tank reactor.
Using a fluidized bed reactor (Fig. 6.3) resolves some of the problems faced with a fixed bed reactor.This particular reactor offers a much more enhanced mass and heat transfer and minimizes temperature gradients throughout the reactor .The mass and heat transfer are improved due to better mixing of the catalyst with the fluid, which provides a greater surface area for the reaction to occur.
