Mathematical model for a fixed bed adsorptive reactor

A new model is proposed to describe the removal of cyanogen chloride from a gas stream passing through a bed packed with activated carbon impregnated with copper, chromium and silver. The model is based on the assumption that the uptake process follows two independent approaches: physical adsorption of CNCl by activated carbon, and a first-order catalytic deactivation reaction of the toxic gas. Four carbon samples were selected to test. The experimental results show that the experimental results conform to this model.
