Abstract:
(EN) The purpose of the present invention is to provide: a method capable of efficiently oxidizing unburned methane at a temperature lower than that of a conventional method by using a catalyst in a mixture gas, such as exhaust gas, comprising oxygen, water vapor and methane; and a catalyst capable of efficiently oxidizing methane, wherein the catalyst comprises: a support having a hydrophobic surface; and an active catalyst metal present in at least a part of the surface of the support, and the temperature at which a methane oxidation reaction occurs can be 300-400°C.
(FR) Le but de la présente invention est de fournir : un procédé capable d'oxyder efficacement du méthane non brûlé à une température inférieure à celle d'un procédé classique en utilisant un catalyseur dans un mélange gazeux, comme des gaz d'échappement, comprenant de l'oxygène, de la vapeur d'eau et du méthane; et un catalyseur capable d'oxyder efficacement le méthane, le catalyseur comprenant : un support ayant une surface hydrophobe; et un catalyseur métallique actif présent dans au moins une partie de la surface du support, et la température à laquelle une réaction d'oxydation du méthane se produit peut être de 300 à 400 °C.
(KO) 본 발명은 배기가스와 같이 산소, 수증기 및 메탄을 포함하는 혼합가스 내에서 촉매를 이용하여 종래 대비 더 낮은 온도에서 미연소 메탄을 효율적으로 산화시킬 수 있는 방법 및 메탄을 효율적으로 산화시킬 수 있는 촉매의 제공을 목적으로 한다. 이때 상기 촉매는 소수성 표면을 가지는 지지체 및 상기 지지체의 적어도 일부의 표면에 존재하는 활성촉매금속을 포함하되, 상기 메탄의 산화반응이 일어나는 온도는 300℃ 내지 400℃ 일 수 있다.
