Abstract
A method is disclosed for synthesizing a reactive sulfur-containing adsorbent material for removing metals, preferably mercury, from hydrocarbon fluids. The method includes impregnating a porous polystyrene resin with elemental sulfur, and heating the impregnated resin/sulfur mixture to chemically fix the sulfur to the resin. The elemental sulfur may be in solid, liquid, or vapor phase under conditions of contact with the resin. Also disclosed is the reactive adsorbent synthesized by this method. Also, a process is disclosed for removing mercury from hydrocarbon fluids by using a reactive adsorbent of the invention.
