Abstract

The present invention is directed to an improved process for removing siloxanes from a biogas feed comprising (i) passing a gas feed through an adsorbent bed having an adsorbent having an inert surface to adsorb onto the adsorbent at least a portion of the siloxanes in the gas feed; and (ii) regenerating the adsorbent by removing siloxanes from the adsorbent. The adsorbent surface is rendered inert or nearly inert preferably via calcination.
