A coconut shell based activated carbon with BET surface area of 795 m2/g, micropore volume 0.37 mL/g and total pore volume 0.44 mL/g was prepared. With this activated carbon as adsorbent, the ventilation air methane (VAM) enrichment by vacuum pressure swing adsorption (VPSA) was investigated. The influence of VPSA parameters such as feed flow rate, effluent flow rate and adsorption time on the performance of the VAM enrichment were examined. The results showed the methane concentration in the simulative VA gas could be enriched by VPSA from 0.52 vol.% to 1.51 vol.% with a methane recovery of 96.3 % at 25 °C and 200 kPa. The methane concentration in effluent gas was reduced to below 200 ppm. The as-prepared activated carbon could be used in the VAM enrichment by VPSA for lean-burn gas turbines.

The depth of sorbate penetration into the adsorbent grains is a new dimensional criterion for estimating efficiency of using the adsorbent in periodic adsorption and desorption processes. The possibility of this criterion utilization in preliminary calculations of oxygen production plants working by the pressure swing adsorption method is shown on the  specific example.
