Selective catalytic reduction of No with methane or ethene on ferrierite-and mordenite-type zeolites containing copper, cobalt and indium

摘要

The selective catalytic reduction (SCR) process of NO int he presence of ferrierite- and moredenite-type catalysts has been studied. Methane and ethene were used as reducing agents. Teh oxidiaing properties of the catalysts were also assessed. The catalytic performance of Cucontaining zeolites was compared for ferrierite, mordenite and ZSM-5 (with ethene). When cobalt and indium ions were present simultaneously in zeolite ferrierite, a pronounced synergetic effect was found in the title reaction using methane.
