Title: Innovative Contributions of Zhihui Gu in Olefin Polymerization
Introduction
Zhihui Gu is an accomplished inventor based in Houston, TX, with a remarkable portfolio, holding 12 patents to his name. His work primarily focuses on advancements in catalyst systems for olefin polymerization, significantly impacting the chemical engineering field.
Latest Patents
Among his latest innovations are two notable patents. The first patent involves high porosity fluorided silica-coated alumina activator-supports and their applications in metallocene-based catalyst systems for olefin polymerization. These activator-supports exhibit a bulk density ranging from 0.15 to 0.37 g/mL, a total pore volume between 0.85 to 2 mL/g, and a BET surface area from 200 to 500 m²/g. The average pore diameter ranges from 10 to 25 nm, with 80 to 99% of the pore volume found in larger pores exceeding 6 nm. This invention includes methods for manufacturing the activator-supports and their role in enhancing catalyst compositions and olefin polymerization processes.
The second patent describes processes for preparing metallocene-based catalyst systems incorporating an alcohol compound. This method comprises contacting the alcohol compound with an organoaluminum compound to create a precontacted mixture, which is then combined with an activator-support and metallocene compound. The resultant catalyst compositions demonstrate enhanced catalytic activity for olefin polymerization, contributing to the efficient production of ethylene-based polymers.
