    Abstract: PROBLEM TO BE SOLVED: To provide a molded catalytic structure having a shape to uniformize the flow velocity of a gas passing through the inside of a catalyst and accordingly having a shape to prolong the service life of the catalyst because of its uniform thermal stress. SOLUTION: The molded catalytic structure has an upstream end face 3, a downstream end face 4 and a circumferential face 5. In this case, the upstream end face is formed in the shape of the side face 8 of a conical or truncated- conical protrusion 7, and the side face 8 has at least a concave curved surface.

    Abstract: PROBLEM TO BE SOLVED: To eliminate the adverse effects of peroxides generated at the cathode of a fuel cell. SOLUTION: The fuel cell 1 has two electrodes 2 and an ion-exchange membrane 6, with each of the electrodes 2 having an electrode catalyst layer 4 and at least one gas passage for a reaction gas 7. The fuel cell contains at least one kind of additive that works to prevent formation of peroxides and/or decompose peroxides. A method is disclosed for using at least one kind of additive inside or over the electrode 2 of the fuel cell 1 having the ion- exchange membrane 6, the electrode catalyst layer 4, and the electrode 2 having at least one gas flow passage for the reaction gas 7. The at least one kind of additive works to prevent formation of and/or decompose peroxides inside or over the electrode 2.

    Abstract: PROBLEM TO BE SOLVED: To provide a spinel monolithic catalyst, manufacturing method therefor and a method of using it for reducing NOx in a waste combustion gas. SOLUTION: This spinel monolighic catalyst contains the spinel shown by general formula I: AxB(1-x)E2O4 (wherein all of A are Cu or half of A or less may be substituted with Co, Fe, Mn or Cr; B is at least one element selected from the group consisting of Zn, Mg, Ca, Zr, Ce, Sn, Ti, V, Mo and W; all of E are Al or half of E or less may be substituted with Fe2O3, Cr2O3, Ga2O3, La2O3 or a mixture of them; and (x) is 0-1, preferably 0-0.9). The spinel monolighic catalyst is obtained by manufacturing a particularly monolithic sintered compact by using the spinel or subsequently covering at least the surface of the sintered compact with an active composition, impregnating the obtained sintered compact with the solution containing transition elements of group V of the periodic table or adding the oxides or salts of these elements to the obtained sintered compact, drying and sintering it.

    Abstract: The invention relates to a method for continuously producing hydroxylammonium salts by catalytically reducing nitrogen monoxide with hydrogen in a diluted aqueous solution of mineral acid in a plurality of series-connected reaction stages. The inventive method is characterized in that the inflow of the diluted aqueous solution of mineral acid is split into at least two partial streams prior to being supplied to the plurality of series-connected reaction stages. A first partial stream is supplied to the first reaction stage. A second partial stream is supplied to a reaction stage other than the first reaction stage, whereby the inflow of diluted aqueous solution of mineral acid into the plurality of series-connected reaction stages is controlled by the pH value of the reaction stage that is not the first reaction stage.

    Abstract: A process for the continuous preparation of hydroxylammonium salts by catalytic reduction of nitrogen monoxide by means of hydrogen in a dilute aqueous solution of mineral acid in a plurality of reaction stages connected in series comprises dividing the incoming stream of dilute aqueous solution of mineral acid into at least two substreams before it is fed into the plurality of reaction stages connected in series, feeding a first of these substreams to the first reaction stage, feeding a second of these substreams to a reaction stage other than the first, where the inflow of dilute aqueous solution of mineral acid into the plurality of reaction stages connected in series is controlled by means of the pH in this reaction stage other than the first.

    Abstract: For a process for the catalytic conversion of fuel for removing oxides of nitrogen from exhaust gases of internal combustion engines, in which fuel and a part- stream of the exhaust gas or of the intake air are converted in a converter, the fuel and the part-stream of the exhaust gas or of the intake air are fed separately from one another into the converter and the fuel is vaporized in the converter. A converter for the catalytic conversion of fuel, comprising a vaporization space and a conversion space connected thereto is furthermore described, the vaporization space having separate feeds for exhaust gas or intake air and fuel, the conversion space having a catalyst for the catalytic conversion of fuel and the vaporization space and the conversion space being connected to one another so that heat transport from the conversion space into the vaporization space is possible.
