Abstract

A mathematical model for pseudo one component adsorption on a fixed bed is developed. The model takes into account of external and internal mass transfer resistances with non ideal plug flow behaviour. In the present study, the Langmuir equilibrium isotherm is used to represent liquid-solid equilibrium relationship. The model consists of a set of couple partial differential equations, and the differential equations representing the mass balances of both fluid and pore phases are solved by the implicit backward Euler finite difference method and compared with previous models reported in literature. The effects of various important and influencing parameters such as flow rate, particle radius and bed porosity in breakthrough curve are studied in detail. Hence, the proposed model is suitable and applicable to study the fixed bed adsorption column performance under isothermal condition.
