Abstract:
A process for the production of a mono-olefin from a feedstock comprising a paraffinic hydrocarbon which process comprises the steps of:(a) feeding a gaseous paraffinic hydrocarbon-containing feedstock and a molecular oxygen-containing gas to an autothermal cracker wherein they are reacted in the presence of a catalyst capable of supporting combustion beyond the normal fuel rich limit of flammability to produce a product comprising one or more mono-olefin(s) and synthesis gas and wherein the autothermal cracker is operated at a temperature greater than 650Â° C. and at a pressure of greater than 5 bar absolute, (b) separating the product from step (a) into a high pressure fuel gas stream comprising methane, carbon monoxide and hydrogen and a stream comprising one or more olefins and recovering the one or more olefin(s), (c) passing the high pressure fuel gas stream comprising methane, carbon monoxide and hydrogen separated in step (b) to a Fischer-Tropsch reactor containing a Fischer-Tropsch catalyst wherein said stream is converted to hydrocarbons, and thereafter recovering at least a part of the hydrocarbon product and wherein the Fischer-Tropsch reactor is operated at a pressure of between 5-50 bar absolute.
