Method of manufacturing open-cell bodies and bodies manufactured using said method
In a method of manufacturing open-cell bodies, individual parts of an open pore plastic in a size which corresponds to the size of the bodies to be manufactured while taking account of the shrinkage on a sintering or an open pore plastic element having predetermined break points which take account of the size and geometrical design of bodies to be manufactured are/is in filtrated and coated with a suspension in which at least one powdery material is contained. Organic components are expelled after a first heat treatment. Subsequently, a sintering is carried out. Parts of porous plastic provided with the suspension are separated before the first heat treatment or wherein, afterwards the open-cell element which is obtained from the plastic element from the material with which the bodies are formed is cut by forces and thereby separated bodies can be obtained.
DENITRIFICATION-OXIDATION COMPLEX CATALYST STRUCTURE AND MANUFACTURING METHOD THEREOF
Proposed inventions are a recipe of denitrification-oxidation complex catalyst containing an SCR catalyst and an oxidation catalyst to simultaneously remove nitrogen oxides, carbon monoxide, hydrocarbons, and ammonia, a manufacturing method thereof, an exhaust gas treatment method using the denitrification-oxidation complex catalyst, and an SCR denitrification system including the denitrification-oxidation complex catalyst. The denitrification-oxidation complex catalyst simultaneously removes nitrogen oxides, carbon monoxide, hydrocarbons, and ammonia and exhibits an increased catalytic effect compared to the cases where the denitrification catalyst used alone and the denitrification and the oxidation catalyst ratios are and not properly balanced. When the denitrification-oxidation complex catalyst is applied to an SCR denitrification system, the structure is simplified, space is saved, cost is reduced, and catalyst maintenance is easy.
