    摘要： The present invention relates to a catalyst support material and catalysts made therefrom having improved resistance towards erosion.The catalyst support contains at least 20% by weight of TiO2 being present mainly in the anatase form. Furthermore, the catalyst support contains diatomaceous earth in an amount of at least 2% and less than 80% by weight of the catalyst support.In one embodiment catalysts made from said catalyst support contain oxides or sulfates of base metals from the group of V, W, Mn, Nb, Mo, Ni, Fe or Cu. Another option is a catalyst prepared from said catalyst support containing Pt or Pd.Said catalysts are used for treatment of a flue gas. More specifically the catalyst supports prepared according to the present invention and showing improved resistance towards erosion are used in flue gas containing a large amount of particulate matter and for selective catalytic reduction of nitrous oxides.

    摘要： A method of decomposing NO2 to NO in an exhaust gas of a lean-bum internal combustion engine comprises the steps of contacting an acidic metal oxide selected from the group consisting of zeolites, tungsten-doped titania, silica-titania, zirconia-titania, gamma-alumina, amorphous silica-alumina and mixtures of any two or more thereof with a gas mixture comprising the exhaust gas, adjusting the composition of the gas mixture, by injecting hydrocarbon therein at a rate that changes over the course of a duty cycle so that, on average over the duty cycle, the C1 hydrocarbon:nitrogen oxides ratio of the gas mixture contacting the acidic metal oxide is from 0.1 to 2.0 and passing the effluent gas directly to atmosphere optionally via first contacting the gas mixture with a hydrocarbon oxidation catalyst.

    摘要： The present invention relates to a coating composition using a catalyst for selective catalytic reduction for the removal of nitrogen oxides from the exhaust gas, a catalytic module element for selective catalytic reduction and a catalytic module for selective catalytic reduction for the removal of nitrogen oxides, and more specifically to a catalytic module element in which and a catalytic module element for selective catalytic reduction in which a plurality of plate-type or waveform glass fiber sheets on which the coating layer of a catalyst for selective catalytic reduction are formed, are repeatedly laminated and a catalytic module for casing the catalytic module element. According to the present invention, the production process is simple, economical and productive and the catalytic module element for selective catalytic reduction is excellent not only in decomposition efficiency of nitrogen oxides in the exhaust gas, but also in durability, economic efficiency and thermal shock resistance. Further, the present invention has an advantage capable of providing a catalytic module that can be used in an operation by directly placing it on the actual spot.
