The influence of the level of H2S in the fuel on catalyst performance was investigated. The main conclusion is that at H2S levels of 30ppm and above, it is probable that the exhaust gas emissions of NGV’s are negatively influenced. Further research is suggested to: 1) Determine the effect of different H2S concentrations on tailpipe emissions. And, if it is found that there is an influence on tailpipe emissions: 2) Determine a maximum fuel H2S content to limit this influence.
