EXHAUST GAS PURIFICATION FILTER AND METHOD FOR MANUFACTURING THE SAME AND EXHAUST GAS PURIFICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an exhaust gas purification filter that can support a catalyst by a simple method without impregnating a filter into a solution including a catalyst particle or coating a filter with a solution including a catalyst particle after manufacturing an exhaust gas purification filter and has high NOx reduction efficiency, to provide a method for manufacturing the filter and to provide an exhaust gas purification device having the filter.SOLUTION: The exhaust gas purification filter is manufactured by sintering a molded product formed from a mixture including zeolite and a raw material particle as a carrier and after sintering, an alkali metal at an ion exchange site of zeolite is exchanged for a transition metal.SELECTED DRAWING: None
