Title: **Innovative Contributions of Inventor YongMan Choi in Riyadh, Saudi Arabia**

Introduction

YongMan Choi is a distinguished inventor based in Riyadh, Saudi Arabia. With a notable portfolio of two patents, Choi has made significant strides in enhancing chemical processes, particularly in the field of hydrocarbon dehydrogenation.

Latest Patents

Choi's recent inventions focus on innovative methods for improving the performance of dehydrogenating alkanes to alkenes. His first patent outlines a process for enhancing the performance of the dehydrogenation of alkanes using CrO as a catalyst. This process involves the oxidation of the catalyst to CrO during dehydrogenation, which is subsequently regenerated using CO as a reducing gas. The regeneration process not only allows for the continuous use of the catalyst but also produces CO, which can be introduced into the dehydrogenation reactor to react with hydrogen produced during the reaction, forming CO and HO through the reverse water-gas shift reaction.

The second patent by Choi reveals a concurrent reduction approach to catalytically dehydrogenate alkanes. In this method, the catalyst is reduced simultaneously with the dehydrogenation process using CO as a reducing agent. Similar to the first patent, this technique generates CO that can react with hydrogen produced from dehydrogenation. Moreover, this patent incorporates a CuO heat-releasing material that enhances the overall efficiency of the reaction by releasing heat during the reduction process.
