  • SCR catalyst for removal of nitrogen oxides
    Patent number: 9662610
    Abstract: The present invention provides for catalysts for selective catalytic reduction of nitrogen oxides. The catalysts comprise metal oxide supporters, vanadium, an active material, and antimony, a promoter that acts as a catalyst for reduction of nitrogen oxides, and at the same time, can promote higher sulfur poisoning resistance and low temperature catalytic activity. The amount of antimony of the catalysts is preferably 0.5-7 wt. %.
    Type: Grant
    Filed: May 19, 2016
    Date of Patent: May 30, 2017
    Assignee: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Heon-Phil Ha, Soon-Hyo Chung, Young-Joo Oh
