Title: The Innovative Contributions of Zhiquan Q. Yan
Introduction
Zhiquan Q. Yan, based in Mt. Pleasant, SC, has made significant contributions to the field of materials science, particularly in the area of activated carbon. With a total of five patents to his name, he is recognized for his innovative approaches to enhancing the performance and manufacturing processes of activated carbon products.
Latest Patents
Yan's latest patents showcase his expertise in developing highly microporous carbons and enhancing their manufacturing processes. One notable patent details a method for chemically activating activated carbon precursors using a potassium hydroxide solution. This process includes carefully pre-drying the blend and activating it at temperatures ranging from 650°C to 1100°C. The resulting microporous activated carbon is remarkable, with more than 50% of its total pore volume comprising pores between 8Å and 20Å in width, and over 70% containing pores less than 20Å in width.
Another of Yan's notable inventions promotes the use of shaped lignocellulosic-based activated carbon. This process involves creating extruded pellets composed of activated carbon particles and inorganic binders. These pellets are designed to enhance performance through tumbling equipment, even before undergoing any thermal processing. The tumbling action not only smooths and densifies the pellets, but it also effectively reduces dust levels associated with the carbon.
