Abstract

PURPOSE: To treat NOx contg. exhaust gas efficiently, economically and advantageously with an inexpensive catalyst which is stable to SOx, by contacting NOx contg. exhaust gas and NH3 gas with a catalyst obtd. by sulfating a mixed composition of lime stone, clay, silica and slag under a heat.
