Title: Innovations of David W Dockter in Chromium Catalyst Activation
Introduction
David W Dockter is a prominent inventor based in Kingwood, TX (US), known for his significant contributions to the field of catalyst activation. With a total of 12 patents to his name, Dockter has made remarkable advancements that enhance the production of ethylene-based polymers.
Latest Patents
Among his latest patents, Dockter has developed systems and methods for chromium catalyst activation. These processes involve producing activated chromium catalysts, such as chromium/silica and titanated chromium/silica catalysts, through a multistep process. This process includes exposure to inert and oxidizing atmospheres at specific temperature conditions. The resulting activated chromium catalysts exhibit unexpectedly high melt index potential, enabling the production of ethylene-based polymers with lower gel counts and higher melt indices. Additionally, related activation systems allow for the adjustment of the fluidizing gas entering the fluidized bed vessel, which can be an inert gas, an oxygen-containing gas, or a mixture of both, to minimize or prevent exotherms.
