    摘要: A catalyst unit (1; 1′) configured for the reduction of NOx compounds in a gas stream and which includes a catalytically active material of the silver/alumina type. The catalyst unit (1; 1′) has at least one first reaction zone (3a, 3b, 3c, 3d, 3e) containing the catalytically active material and at least one second reaction zone (4a, 4b, 4c, 4d, 4e; 8a, 8b, 8c, 8d, 8e) which is arranged to permit breakdown of a gas species which is formed in the first reaction zone (3a, 3b, 3c, 3d, 3e), with N2 being formed, and in that the gas stream is conducted through the first reaction zone (3a, 3b, 3c, 3d, 3e) and the second reaction zone (4a, 4b, 4c, 4d, 4e; 8a, 8b, 8c, 8d, 8e). The invention results in an improved catalyst unit which in particular provides high-grade reduction of NOx compounds in an exhaust gas stream from a combustion engine.

    摘要: Method and apparatus for treating a gas flow including guiding the gas flow through a gas treatment unit (18) adapted for filtering particles in the gas flow, and eliminating the particles in the gas treatment unit (18). Particles are filtered from the gas flow by means of accumulating the particles in, or in connection with, a number of ducts (21) forming part of the gas treatment unit (21) during passage of the gas flow through the gas treatment unit (18). The temperature of the gas flow is controlled along the ducts (21) to a value that provides combustion of the particles, and eliminates the filtered particles in the gas treatment unit (18) by means of combustion in the ducts (21). An improved treatment of a gas flow is provided, in particular in connection with exhaust gas purification in a diesel engine, for eliminating particles in its exhaust gases.

    摘要: Method and apparatus for establishing a fuel cell unit (10) in the form of an extruded monolith having channels (14), of which every second constitutes a fuel channel (14a) and every other second an oxygen channel (14b). The channels (14) are designed in such a manner that the fuel channels (14a) are displaced laterally in relation to the oxygen channels (14b), in such a way that all the fuel channels (14a) protrude a certain distance from the end points of all the oxygen channels 14b) and all the oxygen channels (14b) protrude a certain distance from the end points of all the fuel channels (14a). The distance is less than the length of respective channels. The invention also relates to a fuel cell device that includes several of the fuel cell units (10) that together establish an enhanced system of fuel cell units that lend themselves to compact.
