Competitive siloxane adsorption in multicomponent gas streams for biogas upgrading

摘要

Biogas, produced in anaerobic digesters, is used as a renewable fuel after undergoing several upgrading processes. Adsorption onto activated carbon is the most widely used technology to remove harmful volatile compounds, such as siloxanes. However, the competition for the adsorptive sites with other biogas impurities reduces the performance of the adsorbents increasing the operative costs.
