Introduction

Jun-Seong Ahn is a notable inventor based in Taejon, South Korea. He has made significant contributions to the field of catalysis, particularly in the removal of harmful pollutants. With a total of 4 patents to his name, Ahn's work focuses on developing efficient catalysts that address environmental challenges.

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, with a large specific surface area impregnated with high contents of vanadium. By mixing the spent catalyst with a tungsten-impregnated titania, Ahn has developed a catalyst that exhibits excellent dioxin removal performance and low preparation costs due to the recycling process.

Another significant 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 10% or more increase in efficiency. Additionally, it enhances the efficiency of spent catalyst reclamation by 250%.
