Abstract
1437143 Treating exhaust gases; alumina RHONE-PROGIL SA 5 April 1974 [9 April 1973] 15152/74 Heading C1A [Also in Division B1] Waste gases containing hydrogen sulphide, sulphur dioxide and carbon derivatives of sulphur as impurities are treated for conversion of the impurities to sulphur, water and carbon dioxide in the presence of a catalyst comprising active alumina and 1 to 60% wt. of a titanium compound. calculated as titania, the catalyst having a specific surface area of at least 80 m.<SP>2</SP>/g. and optionally containing a compound of Mo, Co, Ni, Fe or U. In the examples temperatures of 260-335‹ C. and contact times of 1 to 8 seconds are used in the treatment of a gas mixture containing H 2 S, SO 2 , CS 2 , H 2 O and N 2 . The catalytic base is made by impregnating Al 2 O 3 pellets with TiCl 4 and calcining or agglomerating Al 2 O 3 with TiO 2 gel or sol.
