CATALYST CARRIER FOR CATALYTIC REDUCTION OF NITROGEN OXIDES, CATALYST FOR CATALYTIC REDUCTION, AND METHOD FOR CATALYTIC REDUCTION

摘要

PURPOSE:To provide a catalyst carrier effective to remove nitrogen oxides exhaust gas from gas turbine, and to provide a removing method of nitrogen oxides by using a catalyst prepared by ion exchanging or depositing active metal element such as Cu, Fe, etc. CONSTITUTION:The catalytic reduction catalyst for nitrogen oxides is produced by incorporating Fe, Cu and/or Co into a faujasite zeolite carrier. This carrier has 24.43-24.53Angstrom lattice constant, <=10 silica/alumina molar ratio and <=1mum grain size. This catalyst is used for the catalytic reducing method of nitrogen oxides.
