Title: Joon Hyun Baik: Innovator in Catalytic Technology

Introduction

Joon Hyun Baik is a prominent inventor based in Pohang, South Korea. He has made significant contributions to the field of catalytic technology, particularly in the reduction of nitrogen oxides (NOx) in exhaust systems. With a total of 2 patents, his work is recognized for its innovative approaches to environmental challenges.

Latest Patents

One of his latest patents involves a catalyst created by introducing copper ions and cobalt ions into a Y-type zeolite. This CuCoY zeolite enhances the reduction of NOx in exhaust from lean burn engines, such as diesel engines. The invention includes a dual bed selective reduction reactor that effectively reduces NOx by utilizing a first bed of BaY or Ag/alumina and a second bed of CuCoY. The exhaust stream is treated with an oxidant, like ozone, and a reductant, such as diesel hydrocarbons, before passing through the dual bed catalyst.

Another notable patent focuses on a zeolite catalyst and a process for its preparation. This catalyst is designed to remove nitrogen oxides from a gaseous medium across a broad temperature range while maintaining operational and hydrothermal stability at high reaction temperatures. The zeolite catalyst comprises a zeolite carrier with a mole ratio typically ranging from about 14 to about 95, along with copper ions supported on the zeolite carrier. The preparation process involves an ion exchange reaction in a cupric salt aqueous solution at controlled temperatures, followed by drying and calcining the catalyst.
