Description

배기가스 중 일산화질소 환원용 촉매조성물Catalyst composition for reducing nitrogen monoxide in exhaust gas

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도 : 일산화질소 환원제거 장치의 개략도,1 is a schematic diagram of a nitrogen monoxide reduction removal device,

제2도 : 종래의 V2O5－TiO2촉매조성물에 있어서 V2O5의 담지량을 변화시킨 여러 조성물의 일산화질소(NO) 환원율을 온도의 함수로서 그래프화한 도면,2 is a graph showing the reduction rate of nitrogen monoxide (NO) as a function of temperature of various compositions in which the loading amount of V 2 O 5 is varied in a conventional V 2 O 5 -TiO 2 catalyst composition.

제3도 : 본 발명의 Cr2O3－V2O5－TiO2촉매조성물에서 Cr2O3의 담지량을 변화시킨 여러 조성물의 일산화질소(NO) 환원율을 온도의 함수로서 그래프화한 도면.3 is a graph plotting the reduction rate of nitrogen monoxide (NO) as a function of temperature of various compositions in which the amount of Cr 2 O 3 supported in the Cr 2 O 3 -V 2 O 5 -TiO 2 catalyst composition of the present invention is varied.
