A mathematical model of the dynamics of pressure swing adsorption (PSA) process during the separation of multicomponent gas mixtures with the aim of producing hydrogen has been developed. The model allows to calculate the profiles of component concentrations (H2, CO2 and CO) and temperature in gas and solid phases, the pressure and velocity of the gas mixture along the height of the adsorbent depending on time. As a result of the computational experiments, the effect of changes in the temperature, composition, and...
