MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202527095120 A) filed by Chevron Phillips Chemical Company Lp on October 03, 2025, for Methods Of Chromium Catalyst Activation To Reduce Gels And Improve Melt Index Potential.
Inventors include Mcdaniel, Max P.; Gu, Zhihui; Cymbaluk, Ted H.; Ramanathan, Anand; Abrego, Julian; Huber, Taryn L.; and Dockter, David W..
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: Processes for producing activated chromium catalysts such as titanated chromium/silica catalysts are disclosed, and these processes utilize a multistep process involving exposure to inert and oxidizing atmospheres at specific temperature conditions. The resulting activated chromium catalysts have unexpectedly high melt index potential and can produce ethylene-based polymers with lower gel counts in addition to higher melt indices.
