PROCESS FOR PRODUCING ELECTRICITY IN A FUEL CELL SYSTEM

摘要

A process for producing electricity in a fuel cell which comprises: a)pre-reforming a higher carbon (C2+) hydrocarbon fuel in a pre-reformer under conditions effective to achieve substantially complete conversion of higher carbon (C2+) hydrocarbons to produce a pre-reformed fuel stream; b)subjecting the pre-reformed fuel stream to methanation under conditions effective to produce a fuel stream having an increased concentration of methane relative to the pre-reformed fuel stream; and c)supplying the fuel stream and an oxidant to a high temperature fuel cell in which methane is reformed and electricity is produced by reacting the fuel stream at an anode of the fuel cell and reacting the oxidant at a cathode of the fuel cell.
