Method of processing coal gas CALDERON; ALBERT

An improved method for the recovery of elemental sulfur(S) from a coal-gas containing hydrogen sulfide (H 2 S) wherein hot lime (CaO) is used and then regenerated according to the following chemistry: CaO+H 2 S=CaS+H 2 O CaS+3/2 O 2 =CaO+SO 2 SO 2 +C=S+CO 2. These chemical reactions are conducted in-situ while the supply of carbon (C) for the formation of the elemental sulfur(S) is derived
