ABSTRACT:
A gas mixture rich in ethan and/or ethylene is prepared by the conversion of a synthesis gas mixture containing hydrogen, carbon oxides and, optionally, other gases in the presence of one or more gaseous sulphur compounds, in an amount of at least 10 ppm by volume, preferably at least 200 ppm, calculated as H.sub.2 S, utilizing a catalyst consisting of one or more metals of group V-B and/or VI-B of the Periodic Table of Elements, preferably molybdenum and/or vanadium, together with one or more iron group metals each metal being in the form of free metal, oxide, or sulphide, the catalyst being supported on a porous, refractory oxidic support containing titanium dioxide.
There is achieved a high activity and notably a high selectivity for the formation of ethane/ethylene, small amounts of propane, not insignificant amounts of methane and almost full suppression of the formation of higher hydrocarbons.
The invention also relates to the catalyst prepared by impregnation or coprecipitation techniques.
