Résumé
This contribution shows that CH3SSCH3 can be selectively converted into H2S, CH4 and CO2 at 550 °C, using water as a hydrogen donor. CoxOy/γ-Al2O3 could be a valuable candidate as an active and stable catalyst for this process. The results reported in this contribution may be very useful in designing an effective process for cleaning natural gas. The conversion of dialkyl disulfides into hydrocarbons and H2S over CoxOy/γ-Al2O3 without hydrogen could be incorporated into an integrated system comprising well-known technologies, such as the adsorption of mercaptans on solids, MEROX procedure and the absorption of H2S with conventional solvents.
