3336. SHABAKER, H. A. (Houdry Process Corp.) Forming Gaseous Sulfides and Sulfidation. Therewith. United States Patent 2,494,587, Jan. 17, 1950; appl. filed Dec. 4, 1947, Serial No. 789,611; 17 claims (Cl. 252-450). Chem. Abs., vol. 44, 1950, p. 4211.

Application of the invention is shown in the following example: Propane is burned in air to give, after drying, a composition of 1.3 mol. % H₂, 1.6mol. % CO, 12.7% mol. %CO₂ and 84.4 mol. % N₂by vol. The gas is heated to 1,350° F. and 5 mol. % free S is added to the gas stream in finely powdered form or as atomized liquid. The hot mixture is brought in contact with a clay such as acid-activated montmorillonite in pelleted form for 2 hr. The total volume of gas is sufficient to provide H₂S and CS₂ in 4 times the equivalent the oretically required to convert the Fe present in the Clay (2% as Fe2O5) to Fe sulfide. The Fe sulfide is removed from the clay by leaching. 3 United States Patents cited.
