Abstract: front page image
(EN) Provided is a catalyst that, when used in a selective catalytic reduction reaction in which ammonia is the reducing agent, results in good denitration efficiency at relatively low temperatures and does not result in oxidation of SO2. A denitration catalyst that contains at least 3.3 wt% of vanadium oxide in terms of vanadium pentoxide and has a BET specific surface area of at least 10 m2/g.
(FR) L'invention concerne un catalyseur qui, lorsqu'il est utilisé dans une réaction de réduction catalytique sélective dans laquelle l'ammoniac est l'agent réducteur, conduit à une bonne efficacité de dénitration à des températures relativement basses et ne provoque pas d'oxydation de SO2. Le catalyseur de dénitration contient au moins 3;3 % en poids d'oxyde de vanadium en terme de pentoxyde de vanadium et possède une surface spécifique BET d'au moins 10 m2/g.
(JA) アンモニアを還元剤とする選択的触媒還元反応の際、比較的低温での脱硝効率が良いと共に、SOの酸化が伴わない触媒を提供する。 酸化バナジウムが五酸化バナジウム換算で3.3wt%以上存在し、BET比表面積が10m/g以上である脱硝触媒である。
