This paper discusses the effects of desorption pressure on CO2 separation from a simulated mixture of flue gas coming from the process of conventional coal combustion in a power plant by means of the vacuumpressure swing adsorption (V-PSA) technique. The process was carried out in a two-bed installation filled with two granulated adsorbents: (1) zeolite 13X and (2) activated carbon (AC). The effects of feed flow rate and time of the adsorption step also were evaluated. The results obtained in the study suggest a substantial effect of the parameters analyzed on CO2 content in the enriched product, and on the recovery from feed gas.
