摘要

This invention with catalyst active coating, regards the method of covering the catalyst carrier which at least possesses the part structure of 2 where the absorptivity for the coating dispersed liquid differs kinds making use of the coating dispersed liquid. This method modifies the absorptivity of part structure mutually relatively by covering the catalyst carrier extra in the combustion possible material or the liquid, after that applies catalyst coating to the filter body with known method, dries and/or features that calcination it does.
