摘要：
An exhaust gas treatment process useful for the removal of nitrogen oxides using an iron containing zeolite as the catalyst and ammonia as a reducing agent. It is desired to extend the effective temperature range for the selective catalytic reduction (SCR) of nitrogen oxides below about 400.degree. C. This is accomplished in the instant invention through the use of an intermediate pore size zeolite, such as ZSM-5, based catalyst which has been treated to incorporate iron into its pores.
