Abstract
A method of removing siloxanes from a gas stream includes flowing the gas stream that carries siloxanes through an adsorbent media to remove at least part of the siloxanes from the gas stream, wherein the adsorbent media comprises lignite-based activated carbon. A spent adsorbent media is provided that contains the lignite-based activated carbon through which a gas stream containing siloxanes has been at least partially purified, and which may be regenerated.
