Title:
脱硝触媒、及びその製造方法
Document Type and Number:
Japanese Patent JP7429012
Kind Code:
B2
Abstract:
Provided is a catalyst which, when used in a selective catalytic reduction reaction in which ammonia serves as the reducing agent, further improves denitration efficiency at low temperatures compared to the prior art.The denitration catalyst comprises vanadium oxide as a main component, and has a content of a second metal, in terms of oxide, of 1-40 wt%. The second metal is at least one type of metal element selected from the group consisting of Co, W, Mo, Nb, Ce, Sn, Ni, Fe, Cu, Zn, and Mn.
