Biogas purification by means of adsorption on pine sawdust-based activated carbon: Impact of water vapor
Biogas main components besides methane are carbon dioxide and water that often have to be removed to increase the calorific value of the gas.

| Sumario: | Biogas main components besides methane are carbon dioxide and water that often have to be removed to increase the calorific value of the gas. In this study the effect that the presence of water vapor has on CO2 separation from a biogas stream by means of adsorption on a lignocellulosic-based activated carbon is addressed. Binary CO2/CH4 breakthrough experiments at 30 °C to account for competitive adsorption under dry conditions were conducted at several feed compositions and adsorption pressures in a fixed-bed lab set-up. An adsorption selectivity factor was selected for analysis of the different cases. The results indicated that CO2/CH4 separation by adsorption on this material could be most promising at lower pressures. |
