Abstract

Abstract Translated from Japanese (57)【要約】 【課題】炭化水素及び/又は含酸素有機化合物を還元剤 として用いる窒素酸化物接触還元用触媒において、酸素 の共存下においても、そして、特に、酸素、硫黄酸化物 及び水分の共存下においても、窒素酸化物が還元剤と選 択的に反応するため、多量の還元剤を用いることなく、 排ガス中の窒素酸化物を効率よく還元することができ、 しかも、水分の存在下においても、また、高温での使用 においても、耐久性にすぐれる窒素酸化物接触還元用触 媒を提供するにある。 【解決手段】本発明による炭化水素及び/又は含酸素有 機化合物を還元剤として用いる窒素酸化物接触還元用触 媒は、固体酸担体にアルミン酸銀を担持させてなること を特徴とする。 (57) Abstract: A catalyst for catalytic reduction of nitrogen oxides using a hydrocarbon and / or an oxygen-containing organic compound as a reducing agent, even in the presence of oxygen, and in particular, oxygen, sulfur oxides and water. Even in the coexistence of, because the nitrogen oxides selectively react with the reducing agent, without using a large amount of reducing agent, Nitrogen oxides in exhaust gas can be efficiently reduced, In addition, an object of the present invention is to provide a catalyst for catalytic reduction of nitrogen oxides which has excellent durability even in the presence of water and at a high temperature. A catalyst for catalytic reduction of nitrogen oxides using a hydrocarbon and / or an oxygen-containing organic compound as a reducing agent according to the present invention is characterized in that silver aluminate is supported on a solid acid carrier.
