Abstract
Process for producing a mono-olefin from a feedstock containing a paraffinic hydrocarbon comprising 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 650° C. and at a pressure of greater than 5 bar absolute. The product is separated 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). The high pressure fuel gas stream comprising methane, carbon monoxide and hydrogen separated in the second step is passed to a Fischer-Tropsch reactor containing a Fischer-Tropsch catalyst, wherein the stream is converted to hydrocarbons and wherein the Fischer-Tropsch is operated at a pressure of between 5-50bar absolute. Thereafter at least part of the hydrocarbon product is recovered.
