THREE WAY CATALYST USING PYROPHYLLITE MINERALS AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a three way catalyst using agalmatolite and a method for preparing the same and, more particularly, to a three way catalyst using agalmatolite, the three way catalyst having high porosity and a homogeneous pore size, and thus having excellent catalyst supporting capacity, excellent thermal shock resistance, and excellent mechanical strength, and to a method for preparing the three way catalyst, the method using large amounts of agalmatolite to be able to reduce a content of alumina necessary for a cordierite synthesis due to the alumina contained in a large amount in agalmatolite and lowering sintering temperature to reduce raw material costs and fuel costs, thus reducing manufacturing costs.
