Abstract
In this study, bench-scale adsorption experiments have been conducted to investigate the adsorption characteristics of commercially-available adsorbents for the removal of impurities from biogas. The physicochemical properties of adsorbents are first characterized using SEM, XRF and BET analyses followed by the adsorption characteristics analysis of sulfur compounds and siloxanes in adsorbents considered in the present work. It is found that the IHS adsorbent, composing of 85% iron oxide-hydroxide and 5% silica gel, has the best adsorption capacity of hydrogen sulfide, in which its adsorption capacity is almost six times higher than that of iron oxide adsorbent. The IHS has also the highest adsorption capacity for carbonyl sulfide. The best removal efficiency of carbon disulfide has been achieved by both activated carbon and impregnated activated carbon among all of the adsorbents tested. In cases of siloxanes D4 and D5, the silica gel (A2) shows an extremely high adsorption capacity.
