When H[sub 2]S is heated above 600 C in the presence of CO[sub 2], elemental sulfur and synthesis gas are formed. A sulfur-recovery process using this chemistry is as follows: H[sub 2]S is heated in a high-temperature reactor in the presence Of CO[sub 2] and a suitable catalyst. The primary products of the overall reaction are S[sub 2], CO, H[sub 2], and H[sub 2]O. Small amounts of COS, SO[sub 2], and CS[sub 2] also form. Rapid quenching of the reaction mixture to roughly 600 C prevents loss Of… CONTINUE READING
