        Studies were made on the influence of various gases on the removal of organic S compounds from industrial gases.  C2H4 had a deleterious effect on Fe and Al catalysts but not on Ni and Cu at 250°.  At 400° no effect was detectable.  C6H6 had no effect, while C2H2 had a deleterious effect.  Acidic gases, such as CO2 or HCN, transformed CS2 to H2S, especially at high temperature.  A high CO2 content had a deleterious effect at high temperatures.  HCN also had a deleterious effect.  Air, N2, and water vapor gave good results.  Superimposed effects of various impurities were complicated.
