摘要： A method of cleaning an exhaust gas containing nitrogen oxides including passing an exhaust gas through an exhaust gas cleaner comprising a heat-resistant, porous body, which may support a catalyst consisting essentially of (a) at least one alkali metal element; (b) at least one element selected from the group consisting of Cu, Co, Mn and V, (c) at least one rare earth element, and spraying a liquid hydrocarbon into a stream of the exhaust gas on the upstream side of the exhaust gas cleaner, thereby causing atomized and gasified hydrocarbon to function as a reducing agent for reducing the nitrogen oxides in the exhaust gas.

摘要： PURPOSE:To efficiently reduce and remove NOx in exhaust gas by forming a porous ceramic layer having a special specific surface area to the surface of a porous ceramic filter having a specific void and supporting a catalyst on said ceramic layer to form a purifying material and providing the purifying material on the way of an exhaust gas conduit. CONSTITUTION:A porous ceramic layer with a specific surface area of 2m /g or more is formed to the surface of a porous ceramic filter with a void of 20-90% and a catalyst consisting of an alkali metal element and an element selected from Cu, Co and the like is supported on the porous ceramic layer. In this case, the porous ceramic layer is set to 5-20% by wt. of the filter and the catalyst is set to 0.05-3% by wt. of the porous ceramic layer. This gas purifying material is provided on the way of an exhaust gas passage and liquid hydrocarbon is added to exhaust gas on the upstream side of the purifying material and the temp. of the exhaust gas passing through the purifying material is held to 200-500 deg.C. By this method, NOx is effectively removed.

摘要： PURPOSE:To clean effectively an exhaust gas of high oxygen concentration containing particulates, HC, and NOx by arranging cleaning members comprising a porous ceramic layer carrying a catalyst component, a porous ceramic body, a heat resistant porous filter carrying a platinum group element in sequence from the inlet side to the outlet side of the exhaust gas. CONSTITUTION:A porous ceramic layer is installed on a heat resistant porous filter as the first cleaning member on which a catalyst consisting of alkali metals, Cu, etc., rare earth elements is supported. The second cleaning member consists mainly of a porous ceramic body. As the third cleaning member, a heat resitant porous filter carries a platinum group element. These three members are arranged in sequence from the inlet side to the outlet side of exhaust gas. When an exhaust gas of high oxygen concentration containing particulates, HC, and NOx is passed through these cleaning members, particulates are burned at lower temperatures in the first cleaning member, HC is reduced in the second cleaning member, and then the residual HC and CO are oxidized in the third cleaning member, so that the exhaust gas is effectively cleaned.

摘要： PURPOSE:To recondition a filter efficiently without being blinded by providing a filter which catches minute particles floating in exhaust gas, and holding catalyser on the surface of the filter having minute undulations formed thereon. CONSTITUTION:Electrodes 2 having conductivity and porous filters 1 are piled up alternately and held inside a housing 5 through an insulator 4 in the way of an exhaust passage 3. Many minute projections 15 are formed on the surface of each filter 1. Catalyser 17 is stuck on the projections 15. Thus, it is possible to catch and burn minute combustible particles such as particulate and the like in the exhaust gas at any time, and to recondition the filter efficiently without being blinded.

摘要： PURPOSE:To uniformly catch exhaust gas and freely change the volume of a filter by mutually combining many filter elements, and forming inflow ports and outflow ports of exhaust gas through coincidence of respective cutouts arranged on respective flanges. CONSTITUTION:A filter 1 purifying exhaust gas is formed into a columnar shape by piling many disc-like filter elements 3 made of porous ceramics. In this case, on respective flanges 7 formed on respective filter elements 3, respective semi-circular cutouts 9 are arranged on opposite side positions against the center of filter walls 5. Inflow ports 11 and outflow ports 13 of exhaust gas are respectively formed on the connected parts, by coincidence of respective cutouts 9 of respective filter elements 3. Hereby, harmful matter in exhaust gas is caught on respective positions of the filter 1 uniformly and impartially, and also the volume of the filter can be freely changed.

摘要： PURPOSE:To manufacture the body of a cylindrical tube joint simply and easily by forming parts to be expanded at both ends of a cylindrical tube separately by forging and joining them into a body by welding. CONSTITUTION:Parts 3, 3' to be expanded which are to be provided at both ends of the cylindrical main part 2 of a cylindrical tube joint are made if needed by sizing a material 5 of stainless tube worked to a specified size, expanding the end part of the pipe using a die 6 and a punch 7 and thickened using other die and punch to form a forged expanded part. Two such expanded parts 3, 3' are joined to a straight cylindrical main part 2 by welding 4, 4'. A conventional stainless tube cut to a specified length is used as the straight cylindrical main part 2.
