Abstract
Official abstract text for this publication.
An exhaust gas treatment catalyst comprises titanium oxide, tungsten oxide, vanadium oxide, and copper oxide and/or Cu/zeolite-coated catalyst, wherein the catalyst is provided with a nitrogen oxide removing capability in which nitrogen oxides contained in an exhaust gas are subjected to catalytic reduction in the presence of ammonia, and with CO and VOC removing capability.
First claim
Opening claim text (preview).
1 . An exhaust gas treatment catalyst comprising titanium oxide, tungsten oxide, vanadium oxide, and copper oxide and/or a Cu/zeolite-coated catalyst, wherein the catalyst has a nitrogen oxide removing capability in which nitrogen oxides contained in an exhaust gas are subjected to catalytic reduction in the presence of ammonia, and with CO and VOC removing capability. 2 . The exhaust gas treatment catalyst according to claim 1 , wherein the copper oxide is present in an amount of 0.2 to 0.75 wt %. 3 . The exhaust gas treatment catalyst according to claim 1 , wherein the Cu/zeolite-coated catalyst is present in an amount of 50 g to 200 g/m 2 as coating over the base material.
