PROCESS FOR THE PREPARATION OF MONO-OLEFINS FROM PARAFFINIC HYDROCARBONS

摘要

A process for the production of a mono-olefin from a feedstock comprising a paraffinic hydrocarbon which process comprises the steps of: (a) feeding the feedstock and a molecular oxygen-containing gas to an autothermal cracker wherein they are reacted by oxidative dehydrogenation to form a product comprising one, or more, mono-olefin(s) and synthesis gas, (b) separating the product from step (a) into a synthesis gas-containing stream and one, or more, olefins and recovering the one, or more, olefin(s), (c) contacting synthesis gas-containing stream separated in step (b) with either: (i) a catalyst for the conversion of synthesis gas to methanol under conditions whereby synthesis gas is converted to methanol; or (ii) a catalyst for the water gas shift reaction under conditions whereby carbon monoxide in the synthesis gas is converted by reaction with water to hydrogen and carbon dioxide and thereafter recovering hydrogen; or (iii) a catalyst for the conversion of synthesis gas to hydrocarbons under conditions whereby synthesis gas is converted to a hydrocarbon product, and thereafter recovering at least a part of the hydrocarbon product.
