Catalysts and use thereof for removing nitrogen oxides in exhaust gas.

摘要

A catalyst containing a first group of many pores having a diameter of 1 x 10<2> ANGSTROM to less than 1 x 10<3> ANGSTROM and a second group of many pores having a diameter of 1 x 10<3> ANGSTROM to 1.2 x 10<5> ANGSTROM , the pore volume of the first group being at least 10% based on the total pore volume of the first group and the second group, and said catalyst comprising titanium and at least one metal selected from molybdenum, tungsten and vanadium as metal elements of catalytically active ingredients, and the use of the said catalyst for removing nitrogen oxides in exhaust gas are disclosed.
