The present invention relates to a dual bed catalytic system for removing nitrogen oxides, and more particularly, silver supported alumina (Ag / Al 2 O 3 ) and copper supported catalyst; And comprising a reducing agent, here, the volume ratio of alumina and supported copper catalyst is from 1: 1 to 2: 1, and the reducing agent during relates to a dual bed catalyst system for NOx removal, which includes lower alcohols C 1 -5 In the catalyst system of the present invention, the nitrogen oxide removal efficiency is remarkably superior to that of the silver supported alumina catalyst or the copper supported catalyst alone.n n n n Silver Supported Alumina, Copper Supported Catalyst, Ethanol |
