Abstract
PURPOSE: To denitrate exhaust gas consisting NOx and SOx at a high NOxdecomposition ratio by catalytic reduction in the presence of NH3 with molecular sieve catalyst whose ions are exchanged with Cu, Fe, Cr, or Ce ions to an extent the alkali metal ions and alkaline earth metal ions contained in the molecular sieve catalyst are decreased to under specific amounts.
