Abstract: The invention relates to a process for the production of electricity in a fuel cell system by steam reforming a carbonaceous fuel to form fuel cell reactant gas and recycling recovered reactants from the anode exhaust gas to the anode inlet. There is obtained an increase of the electricity production of 20-30% if prior to the recovery and recycling the anode exhaust gas is passed over a steam reforming catalyst by which lower hydrocarbons in said exhaust gas is converted to reactants for use in the fuel. The carbonaceous fuel may for instance be natural gas or methane. A fuel cell system for use in the process comprises supply means (2,10) for carbonaceous fuel; an inlet reformer unit (6) for producing reactant gas for the fuel cell (4); an outlet reforming unit (12) for converting hydrocarbon-containing anode exhaust gas to anode reactant gas; and means (18,90) for recovering the reactant gas and recycling recovered anode reactant gas.

Abstract: The ability of activated carbon to remove mercury and noxious polyorganic matter, especially chlorodibenzodioxins and -furans from incinerator flue gases is utilized in an efficient manner by suspending powdery activated carbon in the flue gas in connection with a conventionel spray absorption process in which the acidic componente of the flue gas are neutralized by means of basic absorbents. The cooling of the flue gases in the spray absorption process provides an efficient adsorption onto the powdery activated carbon and the separation of said powdery activated carbon from the flue gas is substantally facilitated by the presence of the particulate material formed by the spray absorption process. Also an improved removal of nitrogen oxides is obtained.
