WASTE GAS PURIFICATION CATALYST AND METHOD FOR REMOVING NOX

Title:

WASTE GAS PURIFICATION CATALYST AND METHOD FOR REMOVING NOX

Document Type and Number:

Japanese Patent JPH0796194

Kind Code:

A

Abstract:

PURPOSE: To efficiently remove NOx from waste combustion gas contg. oxygen and to enable efficient removal even in the presence of SOx.

CONSTITUTION: This waste gas purification catalyst is made of a zeolite contg. indium and a group Ib metal of the Periodic Table. The molar ratio of SiO2 to Al2O3 in the zeolite is ≥10. In the presence of this catalyst, NOx is removed from waste combustion gas contg. oxygen by using a hydrocarbon.
