Abstract:
1. A method for producing a heavier hydrocarbon stream from a light hydrocarbon stream using an oxidant stream comprising oxygen as an oxidant in a catalytic partial oxidation reactor to form a synthesis gas and converting the synthesis gas in a Fischer-Tropsch process using a Fischer-Tropsch reactor and supported catalyst to produce heavier paraffins, the method comprising: a. compressing and heating the oxidant stream; b. heating the light hydrocarbon stream; c. supplying the oxidant and hydrocarbon streams to a catalytic partial oxidation reactor to form the synthesis gas, the catalytic partial oxidation reactor comprising two chambers separated by a porous ceramic wall, where the porous ceramic wall contains or supports a partial oxidation rhodium on alumina catalyst and wherein the porous ceramic wall is a cylindrical structure which has a porosity from 10% to 50% and has a pore size that is from 200 nm to 20,000 nm and is from 1 mm to 10 mm thick, and the oxidant and hydrocarbon molar flows are in the ratio of approximately about 1:2 and the oxidant is introduced predominantly into one chamber and the hydrocarbon is introduced predominantly into the second chamber; d. cooling the produced synthesis gas to condense water and separating the water; e. passing the dried synthesis gas without further compression to the Fischer-Tropsch reactor; f. converting the dried synthesis gas in a fixed bed, structured catalyst reactor where catalyst particles are fixed on a porous support and there is forced flow of the dried synthesis gas through the supported catalyst and porous support to produce a hydrocarbon stream and a gaseous stream comprising light hydrocarbons, hydrogen, carbon monoxide, water; and g. recovering a product stream comprising light and heavy hydrocarbons, hydrogen and carbon monoxide.
