Method for preparing a catalyst for selective catalytic reduction of nitrogen oxides at high temperature window |
摘要 |
Disclosed is a method for preparing a catalyst for selective catalytic reduction of nitrogen oxides at high temperature window. The catalyst is prepared by recycling a spent catalyst discharged from a hydro-desulfurization process of an oil refinery in which the spent catalyst comprises an alumina support with a large specific surface area impregnated with low contents of vanadium and high contents of molybdenum. The thus prepared catalyst has more excellent selective removal activity of nitrogen oxides at a high temperature window by containing suitable amounts of metal components therein as well as a better poisoning resistance to sulfur oxides, compared with the conventional catalysts.
