ABSTRACT

This study has been a focus on NO decomposition on metal-incorporated SAPO-34(MeAPSO-34) under the reaction condition of oxygen presence with various hydrocarbons. Used materials with various transition metal ions were synthesized by rapid crystallization method. As a result in characteristics, these materials were attained as a uniformly regular form with sharp distribution in particle size. The performances for NO decomposition on these materials were exhibited variously according to the properties of metals. As a surprising result, the NO decomposition on the metal incorporated materials was enhanced compared with on the non-metal material. In particular, the Ni-incorporated SAPO-34 material exhibited good performance in NO conversion with presence of CsHe at high temperature, and that on FeAPSO-34 increased at low temperature. In addition, it was confirmed that their performance for NO decomposition has closely influenced on hydrocarbon species.
