    摘要： A Selective Catalytic Reduction (SCR) catalytic converter that does not require the injection of a reducing agent, and, particularly, to an open-flow type or wall-flow type SCR catalytic converter that does not require the injection of a reducing agent, which includes a front portion, in which first supports supporting modified catalyst components are applied on the inner surfaces of porous partition walls, a middle portion, in which second supports supporting ammonia synthesis catalyst components are applied on the inner surfaces of porous partition walls, and a rear portion, in which third supports supporting SCR reducing catalyst components are applied on the inner surfaces of porous partition walls. The catalytic converter can improve a reduction rate of NOx without requiring the injection of an ammonia reducing agent from the outside.

    摘要： Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.
