Claim:
1. A process for removing mercury from a feedstock fluid comprising: separating a feedstock fluid comprising mercury and containing oxygen into a liquid phase and a gaseous phase; passing the liquid phase through an liquid purifier bed containing adsorbent particles comprised of crystallites of a zeolitic molecular sieve having pore diameters of at least 3.0 angstroms and in which the said zeolite crystallites are formed into an aggregate cylindrical or beads which contain elemental silver, whereby mercury is adsorbed and a liquid effluent stream is recovered from the liquid purifier bed; passing the gaseous phase through a gas purifier bed containing adsorbent particles comprised of crystallites of a zeolitic molecular sieve having pore diameters of at least 3.0 angstroms and in which the said zeolite crystallites are formed into an aggregate cylindrical or beads which contain elemental silver, whereby mercury is adsorbed and a gas effluent stream is recovered from the gas purifier bed; and, regenerating the gas purifier bed by the passage as a purge gas therethrough of a portion of the gas effluent stream, the liquid effluent stream, or both; and, regenerating the gas purifier bed by the passage as a purge gas therethrough of a portion of the gas effluent stream, the liquid effluent stream, or both.
