Abstract:
     Semi-water gas or water gas whose sulfide content is greater than 0.08 g/cu.m is purified by middle-temp Fe-Cr catalyst or Co-Mo purifier and then converted at low temp by Co-Mo sulfur-resisting catalyst while steam is delivered in to make the CO concentration in converted gas meet the requirement on copper's purification or methanation under reasonable control of temp and conversion. Said process features the lowest fractional pressure of hydrogen sulfide in counter-sulfurization reaction and efficient catalysis reaction under the lowest sulfide concentration.
