摘要： Nitrous oxide contained in a gas is directly decomposed by contacting the gas with a catalyst layer composed mainly of tin (IV) oxide at a reaction temperature of not less than 250.degree. C., preferably not less than 300.degree. C. Particularly when a cobalt (II) compound is added to the catalyst layer, nitrous oxide can be effectively removed to a low concentration by contacting the gas with the catalyst layer at the reaction temperature of not less than 200.degree. C., preferably not less than 300.degree. C. By the present process, nitrous oxide which has not conventionally effectively removed can be reliably removed at a low cost. The present process can be applied for the removal of nitrous oxide in exhaust gases discharged from a sludge-incinerating furnace, a boiler fine powder coal combustion furnace, etc.

摘要： An organic halogen compound-decomposing catalyst is provided, which affords excellent decomposing percentages even at low temperatures, and reduces the possibility of re-synthesizing dioxins and brominated dioxins. An organic halogen compound-decomposing catalyst is obtained by reacting a Pt salt and/or a Pd salt, an alkoxide derivative of Ti compound and an amino acid as an organic binder in a solvent, thereby synthesizing an organic metal precursor containing Pt and/or Pd and Ti in molecules thereof, and heating the organic metal precursor. This catalyst may be carried on a surface of a clean side of a ceramic filter. Since active points can be increased by uniformly dispersing the Pt and/or Pd particles in Ti particles, the catalyst has higher activity as compared with conventional catalysts, and exhibits excellent decomposing effects even at temperatures lower than 200° C.

摘要： A method for removing nitrogen oxides and organic chlorine compounds from a combustion waste gas, which comprises the steps of: adding ammonia (NH.sub.3) as a reducing agent to a combustion waste gas containing nitrogen oxides and organic chlorine compounds; causing the combustion waste gas added with ammonia to contact with, while keeping the temperature of the combustion waste gas within a prescribed range, with a catalyst comprising at least one selected from the group consisting of platinum (Pt), palladium (Pd), ruthenium (Ru), manganese (Mn), copper (Cu), chromium (Cr) and iron (Fe) and oxides thereof, supported on the surface of a carrier comprising at least one selected from the group consisting of titanium oxide (TiO.sub.2), silicon oxide (SiO.sub.2), aluminum oxide (Al.sub.2 O.sub.3) and zirconium oxide (ZrO.sub.2), thereby removing nitrogen oxides and organic chlorine compounds from the combustion waste gas.

摘要： An adsorbent and process for producing an absorbent capable of decomposing an organic halogen compound, is provided. The adsorbent can adsorb organic halogen compounds contained in waste gases and can assuredly decompose them without synthesizing them. A salt of Pt and/or Pd, an organic titanium compound and an organic binder are reacted in a solvent, to thereby synthesize a dispersion of an organic metal compound precursor containing Pt and/or Pd and Ti in molecules thereof, a sol of TiO2 is added to the dispersion to prepare a catalyst-coating solution, an activated carbon is impregnated with the catalyst-coating solution, and the resulting mixture is heated, thereby allowing the activated carbon to carry thereon an organic halogen compound-decomposing catalyst comprising TiO2 and, dispersed therein, fine particles of Pt and/or Pd. In a low temperature range of 130 to 150° C. in which the activated carbon is usable, organic halogen compounds in the exhaust gases can be decomposed, and SOx, NOx, HCl and heavy metals can be removed through adsorption.
