Title: Innovations of Sang-Ho Lee in Environmental Catalysis
Introduction
Sang-Ho Lee is a prominent inventor based in Taejon, South Korea. He has made significant contributions to the field of environmental catalysis, holding a total of 7 patents. His work focuses on developing catalysts that effectively reduce harmful emissions, particularly dioxins and nitrogen oxides.
Latest Patents
One of his latest patents is a catalyst for removing dioxin and a preparation method thereof. This innovative catalyst is prepared by recycling a spent catalyst discharged from a hydro-desulfurization process of an oil refinery. The spent catalyst comprises an alumina support, preferably gamma alumina, which has a large specific surface area and is impregnated with high contents of vanadium. By mixing the spent catalyst with a tungsten-impregnated titania, a catalyst with excellent dioxin removal performance and low preparation cost is achieved due to the recycling process.
Another notable patent is for a catalyst for selective catalytic reduction of nitrogen oxides and a method for preparing the same. This catalyst is prepared using spent catalysts that have absorbed vanadium, nickel, and sulfur in the hydro-desulfurization line of an oil refinery. The catalyst can remove nitrogen oxides at a level of 90% or higher, demonstrating a significant increase in efficiency. Additionally, it enhances the efficiency of spent catalyst reclamation by 250%.
