MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202418044139 A) filed by Chevron Phillips Chemical Company Lp on June 07, 2024, for Preparation Of Large Pore Silicas And Uses Thereof In Chromium Catalysts For Olefin Polymerization.
Inventors include Mcdaniel, Max P.; Clear, Kathy S.; Ash, Carlton E.; Kelly, Stephen L.; and Allemand, Amanda B..
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: Silica composites and supported chromium catalysts having a bulk density of 0.08 to 0.4 g/mL, a total pore volume of 0.4 to 2.5 mL/g, a BET surface area of 175 to 375 m2/g, and a peak pore diameter of 10 to 80 nm are disclosed herein. These silica composites and supported chromium catalysts can be formed by combining two silica components. The first silica component can be irregularly shaped, such as fumed silica, and the second silica component can be a colloidal silica or a silicon-containing compound, and the second silica component can act as a glue to bind the silica composite together.
