CATALYST CARRIER FOR SELECTIVE CATALYTIC REDUCING WHICH INCLUDES A FIRST UNIT CATALYST CARRIER WHICH INCLUDES A FIRST AND A SECOND FLAT TYPE METAL FOAM AND A NONPLANAR TYPE THIRD METAL FOAM WHICH IS ARRANGED BETWEEN THE FIRST AND THE SECOND FLAT TYPE METAL FOAM

摘要

PURPOSE: A catalyst carrier for selective catalytic reducing which has a three-dimensional reaction structure is provided to minimize the volume and the weight of the catalyst carrier by increasing the reactive surface which enable NH3 reacts with NOx per unit volume.;CONSTITUTION: A catalyst carrier for selective catalytic reducing has three-dimensional reaction structure which the catalyst for the selective catalytic reduction is coated. The catalyst carrier comprises a first unit catalyst carrier (100) which includes the first and second flat type metal foams (110,120); and a nonplanar type third metal foam (130). The first and second metal foam have a fixed size and a fixed shape; and arranged with regular intervals. The nonplanar type third metal foam is arranged between the first metal foam and the second metal foam.;COPYRIGHT KIPO 2013
