DOPED CERIA-CONTAINING ZEOLITE-BASED NH3 SCR CATALYST

摘要

A catalyst for catalysing the selective reduction of NOx with NH3 comprises an alumino-silicate zeolite supporting doped ceria. Suitable dopants include zirconium, lanthanum, alumina, yttrium, praseodymium, neodymium or any mixture of two or more thereof. The catalyst can be used for treating gas streams form stationary power sources such as coal or petroleum fired power plants or boilers, gas turbines or a diesel engines.
