Abstract: PURPOSE: An integrated catalyst purifier is provided to reduce not only a nitrogen oxide in the exhaust gas of a diesel engine but also a particulate material at the same time, reduce the number of the components of a vehicle by simplifying the structure of ventilation post processing equipment, improve productivity by easily mounting, and purify the exhaust gas of a diesel vehicle. CONSTITUTION: An integrated catalyst purifier includes an induction pipe(110) in which the exhaust gas of a diesel vehicle is flowed in; a filter(101) for removing a particulate material; and a discharge pipe(150) for discharging an exhaust gas. The filter for removing a particulate material is equipped with multiple cells having a regular length segmented by a cell wall. The filter for removing a particulate material has a catalyst coating part for LNT(120) and a catalyst coating part for SCR(140) in which a catalyst for LNT (Lean NOx Trap) and SCR (Selective Catalytic Reduction) are successively coated from the front end to the back direction in the cell wall. The catalyst coating part for LNT oxidizes the hydrocarbon, carbon monoxide, volatile material, nitrogen oxide of the exhaust gas, and generates ammonia which is nitrogen and a intermediate product by the reaction of a hydrocarbon which is a reducing agent and an occluded nitrogen oxide. The catalyst coating part for SCR removes an unpurified nitrogen oxide by using the ammonia generated in the catalyst coating part for LNT.

Abstract: PURPOSE: An integrated type catalyst purifying apparatus is provided to simultaneously reduce particulate materials and nitrogen oxide materials from the exhaust gas of diesel engines and to minimize the volume of a catalytic apparatus. CONSTITUTION: Exhaust gas is introduced through an introducing pipe(110). A filter(101) for eliminating particulate materials eliminates particulate materials from the exhaust gas. An exhausting pipe(150) discharges the purified exhaust gas through the filter to outside. A lean NOx catalyst(LNT) coating part oxidizes hydrogen carbide, carbon monoxide, volatile materials, and nitrogen monoxide. During the oxidization, the hydrogen carbide and nitrogen oxides are reacted to generate ammonia as an intermediate product. A selective catalytic reduction catalyst coating part uses the ammonia from the LNT coating part to eliminate non-purified nitrogen oxide materials.
