Abstract
Process for the production of a mono-olefin and a hydrocarbon fraction boiling in the diesel range in which (I) a gaseous paraffinic hydrocarbon-containing feedstock and a molecular oxygen-containing gas are fed to an autothermal cracker wherein they are reacted in the presence or absence of a catalyst capable of supporting combustion beyond the normal fuel rich limit of flammability under conditions whereby the feedstock is oxidatively dehydrogenated to a product comprising one or more mono-olefin(s) and synthesis gas. The product from step (I) is separated into synthesis gas and one or more mono-olefin(s) and the one or more mono-olefin(s) are recovered. Synthesis gas separated in step (II), optionally together with additional synthesis gas, is fed to a Fischer Tropsch (FT) reactor containing an FT catalyst wherein the synthesis gas is reacted under FT conditions to produce an FT product containing naphtha and hydrocarbons boiling in the diesel range.
