Latest Patents
Kyung-Il Choi's latest patents include innovative methods for preparing catalysts that enhance the selective removal of nitrogen oxides. One of his patents describes a method for preparing a catalyst for the reduction of nitrogen oxides. This catalyst is created by recycling a spent catalyst from a hydro-desulfurization process in oil refineries. The spent catalyst features an alumina support with a large specific surface area, which is impregnated with low contents of vanadium and high contents of molybdenum. The resulting catalyst demonstrates superior selective removal activity of nitrogen oxides at high temperatures and exhibits better resistance to poisoning by sulfur oxides compared to conventional catalysts.
Another significant patent focuses on a method for preparing a catalyst specifically for selective catalytic reduction of nitrogen oxides. This catalyst is also derived from a spent catalyst from a hydro-desulfurization process, containing vanadium, nickel, molybdenum, and sulfur components on alumina, along with a tungsten-impregnated support. The catalyst prepared through this method shows excellent selective removal effects of nitrogen oxides and improved resistance to sulfur oxides.
