Title: Innovations of Yanning Cao in Catalyst Development

Introduction

Yanning Cao is a notable inventor based in Fuzhou, China, recognized for his contributions to the field of chemical catalysts. With a total of two patents to his name, he has made significant advancements in catalyst technology, particularly in the areas of CO shift catalysts and their preparation processes.

Latest Patents

Yanning Cao's latest patents include a CO shift catalyst carrier and a sulfur-tolerant CO shift conversion catalyst. The first patent presents a catalyst carrier that boasts shift and adsorption purification performance. This innovative carrier is composed of modified bauxite, which enhances its mechanical strength and anti-hydration capacity. The modification process removes most iron oxide from the bauxite, resulting in a high concentration of active aluminosilicate compounds. These compounds facilitate the migration of magnesium and aluminum ions during the calcination process, leading to the formation of MgAlO at lower temperatures. Additionally, the catalyst carrier's structure allows for the formation of macro pores, enhancing its ability to adsorb and purify macromolecular particles, including oil pollution and dust.

The second patent details a sulfur-tolerant carbon monoxide shift conversion catalyst. This catalyst is prepared using a combination of magnesium and aluminum sources, oxide flux, crystal growth agents, and rare earth additives. The preparation method involves several steps, including kneading, extruding, drying, and calcining the mixture to create a catalyst carrier. The incorporation of nano-sized active components significantly improves the catalytic activity and stability of the catalyst.
