Title: Kwang-Chul Hyun: Innovator in Nitrogen Trifluoride Refinement
Introduction
Kwang-Chul Hyun is a notable inventor based in Anyang-si, South Korea. He has made significant contributions to the field of gas refinement, particularly focusing on nitrogen trifluoride. With a total of 2 patents to his name, Hyun's work is recognized for its innovative approaches to improving gas purification processes.
Latest Patents
Hyun's latest patents include two processes for refining nitrogen trifluoride gas using alkali earth metal exchanged zeolite. The first patent discloses a method where nitrogen trifluoride (NF3) gas, containing carbon tetrafluoride (CF4) as an impurity, is permeated into a bed of zeolite 3A, 4A, or 5A. This zeolite is ion exchanged with alkali earth metal and thermally treated at temperatures ranging from 150 to 600°C for a duration of 0.5 to 100 hours. This process selectively adsorbs nitrogen trifluoride onto the zeolite bed, followed by its desorption. The second patent outlines a similar process but involves both ion exchange and impregnation of the zeolite with alkali earth metal, enhancing the selective adsorption of nitrogen trifluoride.
