Abstract (EN): The importance of heat effects in an adiabatic bed during the pressurization and blowdown steps of pressure swing adsorption (PSA) processes is assessed. The compression energy is included in the energy balance. The effect of the temperature fluctuations on the separation results is much more important than the effect of the adsorption capacity. It is very important and useful to improve the bed dynamics by using high-heat-capacity adsorbent particles or heat exchange in order to reduce the temperature fluctuations in PSA processes as suggested by R.T. Yang and P. Cen (Ind Eng Chem Des Dev (1986) 25 54-59)1. © 1992.
