Patent number: 4085195Abstract: Process for preparing surface impregnated catalysts and sorbents, and flue gas desulfurization process using the same. The sorbent is produced by pre-soaking a porous solid particulate carrier material in a polar organic liquid such as a C.sub.5 -C.sub.10 alcohol, immersing the carrier without drying in an impregnating solution for a time sufficient to permit the impregnating solution to penetrate to a controlled depth without totally impregnating the carrier, and drying and calcining the impregnated carrier, whereby a contact material having an inner zone of substantially unimpregnated carrier and an outer zone of carrier impregnated with active material is produced. Sulfur dioxide is removed from flue gas by contacting the flue gas with a sorbent thus prepared. The preferred carrier for flue gas desulfurization is alumina and the preferred active material is copper oxide.Type: GrantFiled: June 5, 1974Date of Patent: April 18, 1978Assignee: Exxon Research & Engineering Co.Inventors: Neville L.
