Recently, the regulation of atmospheric pollution has been strengthened due to the occurrence of problems such as particulate matter (PM). Nitrogen oxides (NOX), which are the major cause of PM, are generated in the combustion gases of thermoelectric power plants and the diesel engines. Among the flue gas removal technologies, selective catalytic reduction (SCR) is being used worldwide to high de-NOX efficiency. However, the serious drawback of SCR is oxidation to SO2-SO3 and narrow operation temperature range 300~380℃.
The aim of this study, we confirm the promoting effect by adding transition metals such as zirconium (ZrO2), iron (FeO3), Ceria (CeO2) and tungsten (WO3) to the vanadium based catalyst. Moreover, we investigated a corrugated type catalyst by slurry coating and examined its catalytic properties. The catalyst exhibited an excellent performance (>85%) and high durability against sulfur and H2O in simulated power plant condition.
