Abstract
PURPOSE: To obtain a filter which has good capturing efficiency and is free from clogging in a honeycomb-like filter carrier having cells which are held closed at one end by forming activated alumina surfaces on the wall surfaces of the cells then depositing catalytic components thereon.
CONSTITUTION: A honeycomb body consisting of a porous inorg. sintered body is used for a filter 1 for removing fine particles such as carbon contained in waste gases. The cells 1a constituting this are closed at either one end so that the open ends and the closed ends are placed adjacent to each other. Activated alumina layers are formed on the wall surfaces of such cells 1a to deposite catalyst component on this alumina layers. Then, the fine particles in the waste gases can be captured by the microholes of the cells and walls and since they are burned by the catalysts, the filter of good capturing rate and purification rate is obtained.
