Adsorption process design mass-transfer zone

It is fortunate that for many fixed bed adsorption processes of commercial interest the shape of the mass transfer zone remains unaltered as it progresses through the majority of the bed because this leads to substantial simplifications in design. For a favourable isotherm, particularly one of Type I, the mass transfer wave spreads from a shock front as it progresses through the initial region of the bed. As explained earlier in this chapter the...
