Abstract

1511911 Removing sulphur oxides EXXON RESEARCH & ENG CO 2 May 1975 [22 July 1974] 18453/75 Heading C1A Sulphur oxides are removed from a gas mixture, e.g. flue gas by contact with a sorbent comprising (a) copper and/or copper oxide, (b) a carrier comprising a major proportion of Al 2 O 3 and which has not been exposed to a temperature above 1400‹ F. and (c) MgO at least a part of which is on the carrier surface. The sorbent may be formed by impregnating the carrier with Mg salt, heating to convert to MgO, filling the pores of the material with C 5 -C 10 alkanol, contacting with Cu salt solution and again heating. Alternatively the pores of the Al 2 O 3 may be liquid-filled before contact with mixed Mg and Cu salt solution. In examples, SO 2 is separated from N 2 containing also O 2 and H 2 O.
