A system is provided in which particulates and sulfur oxides are simultaneously removed from flue gases in a granular bed filter with special sulfur oxide-capturing and particulate-removing material. The spent sulfur oxide-capturing and particulate-removing material can be regenerated in a lift pipe

A system is provided in which particulates and sulfur oxides are simultaneously removed from flue gases in a granular bed filter with special sulfur oxide-capturing and particulate-removing material. The spent sulfur oxide-capturing and particulate-removing material can be regenerated in a lift pipe riser.

A gas purification system, comprising: a vessel comprising a housing defining and positioned about a vertical axis, a plurality of conduits connected to and communicating with said housing, said conduits including a gas inlet, a gas outlet, an adsorber inlet and an adsorber outlet, said gas inlet comprising a downwardly facing gas inlet being positioned at an angle of inclination ranging from about 30°to about 90°relative to a horizontal axis for feeding and directing the flow of influent gases generally downwardly through said housing, an annular frustoconical adsorber collection reservoir positioned within said housing, said reservoir having flared sidewalls extending below the height of said gas inlet, and discharge chutes communicating with said reservoir comprising substantially symmetrical inclined chutes extending downwardly and outwardly from said reservoir at an angle of inclination relative to said vertical axis in a direction away from said gas inlet; sulfur oxide and particulate removal balls located in said reservoir, inclined chutes, and housing for simultaneously removing a substantial portion of particulates and sulfur oxides from a gaseous stream in said housing, said sulfur oxide and particulate removal balls entering and exiting said housing through said absorber inlet and absorber outlet, respectively; and said sulfur oxide and particulate removal balls including a bed of sulfur oxide-capturing and particulate-removing balls selected from the group consisting essentially of adsorbers and adsorbers with at least one promoter thereon, said adsorbers being substantially present in the absence of a carbonaceous aggregate and comprising an oxide of at least one metal selected from the group consisting of aluminum, bismuth, manganese, yttrium, antimony, tin, a rare earth metal, a Group 1a metal, and a Group 2a metal, and said promoter selected from the group consisting essentially of a rare earth metal, a Group 8 metal, chromium, vanadium, rhenium, and combinations thereof.
