Abstract
A process is described for converting carbon oxylsulfide and/or carbon disulfide, possibly in combination with hydrogen cyanide, O.sub.2 and/or SO.sub.2 in a reducing CO containing gas stream by the catalytic hydrolysis of COS and CS.sub.2, followed by the removal of H.sub.2 S, present and formed, from the gas stream. According to the invention, the process is characterized by (a) a first stage comprising converting a portion of the CO present with water in the presence of a catalyst with simultaneous or subsequent hydrogenation of any O.sub.2 and/or SO.sub.2 that may be present; (b) a second stage comprising catalytically hydrolysing COS and/or C.sub.2, possibly in combination with HCN in the gas stream, with water; and (c) a third stage comprising removing substantially all sulfur components from the gas stream; the catalytic conversion of CO in stage (a) being effected so that the heat thereby produced is substantially sufficient to raise the temperature of the gas stream to the value required for the hydrogenation and for the second stage.
