Latest Patents

Sun is named on one patent, 1 patent: “Olefin Polymerization Method and System.” The invention combines supported dual catalysts with a series process involving two reactors. A liquid material produced through heat exchange and gas-liquid separation is introduced into a first reactor, where it contacts the catalysts and undergoes polymerization. The reaction material and the first polyolefin then enter a second reactor for further polymerization.

The process enables particles to circulate between the reactors, improving the mixing of polyolefins with substantially different properties and helping prevent phase separation. Introducing ethylene gas into the first reactor also lowers the hydrogen-to-ethylene ratio, which can increase polyethylene’s molecular weight and improve product performance.
