Title: Process for the manufacture of carbon disulphide

Abstract: The invention provides a process for the manufacture of carbon disulphide comprising supplying a molecular oxygen-containing gas and a feedstock comprising a hydrocarbonaceous compound to a reaction zone containing a liquid elemental sulphur phase and reacting, in the liquid sulphur phase, at a temperature in the range of from 300 to 750.degree. C., the hydrocarbonaceous compound with elemental sulphur to form carbon disulphide and hydrogen sulphide and oxidizing at least part of the hydrogen sulphide formed to elemental sulphur and water. The invention further provides the use of a liquid stream comprising carbon disulphide, hydrogen sulphide and carbonyl sulphide obtainable such process for enhanced oil recovery.
