CATALYST FOR TREATING EXHAUST GAS AND DEVICE FOR TREATING EXHAUST GAS USING THE SAME

摘要

A catalyst for treating an exhaust gas having at least a carrier and plural layers formed on said carrier, wherein at least one layer of the above plural layers has an interstice in said layer, and at least one layer of the above plural layers contains a catalyst component. The above catalyst for treating an exhaust gas allows the enhancement of diffusion of an exhaust gas in a catalyst layer, which results in the improvement of catalyst efficiency.
