The present disclosure is generally directed to a new and innovative system, process and method that utilize a new “non-oxygen type of oxidizers” process for methane (CH.sub.4) upgrading to value-added products such as olefins and aromatics (i.e., benzene, toluene and xylene (BTX)) etc. and further removing toxic impurities such as sulphur-containing compounds (i.e. H.sub.2S) by using the sulphur as a source of radical.

The present invention relates to a method for preparing methyl mercaptan, in batches or continuously, preferably continuously, said method including at least the following steps: a) reacting at least one hydrocarbon feedstock in the presence of hydrogen sulphide (H.sub.2S) and optionally sulphur (S) such as to form carbon disulphide (CS.sub.2) and hydrogen (H.sub.2); b) reacting said carbon disulphide (CS.sub.2) by hydrogenation in the presence of said hydrogen (H.sub.2) obtained in step a) such as to form methyl mercaptan (CH.sub.3SH), hydrogen sulphide (H.sub.2S) and possibly hydrogen (H.sub.2); c) optionally recirculating said hydrogen sulphide (H.sub.2S) formed during step b) to step a); and d) recovering the methyl mercaptan.
