Latest Patents

Al-Enazi's latest patents include a groundbreaking ethylene gas phase polymerization process. This invention relates to a gas phase polymerization process for the production of ethylene polymers using a catalyst composition based on chromium and titanium compounds, along with a silica support material. The silica support material is characterized by a surface area between 685 m/g and 800 m/g, a pore volume between 1.65 and 1.85 cm/g, and an average particle size ranging from 25 to 35 micrometers. The catalyst composition is introduced into the polymerization reactor via a dry catalyst feeder.

Another notable patent is the process for transitioning between incompatible catalysts. This invention outlines a method for transitioning from a continuous polymerization reaction of ethylene and a first comonomer, producing linear low-density polyethylene with a Ziegler-Natta catalyst, to a second continuous polymerization reaction of ethylene and a second comonomer, resulting in high-density polyethylene with a chromium-based catalyst. The process involves several steps, including adjusting the feed of the first comonomer, maintaining polymerization conditions, and carefully managing the introduction of catalysts and comonomers.
