Catalyst composition with cr coated silica support for polyethylene production
The patent application (Publication Number: US20230365725A1) discloses a catalyst composition for polymerizing ethylene, comprising a silica-containing substrate derived from a base-set gel. The composition includes a catalytically active metal with specific amounts of Cr, Al, and Na. The catalyst composition is designed with precise ratios of these elements to optimize its catalytic activity. The method of preparing the catalyst composition involves a series of steps, including an acid-base reaction, treatment of the hydrogel precursor to reduce the amount of Al, and impregnation with a chromium compound. Additional steps such as crushing the hydrogel precursor and adjusting the Na content are also included to enhance the catalyst's performance.
Furthermore, the patent application describes a method for polymerizing ethylene using the catalyst composition, which involves activating the catalyst with thermal steps. The activation process includes heating the catalyst at a specific temperature range for a defined period in a fluidized bed reactor. The method is specifically tailored for producing high-density polyethylene (HDPE) suitable for small blow molding applications. By carefully controlling the composition and activation of the catalyst, the method aims to improve the efficiency and quality of the polymerization process, resulting in enhanced performance of the HDPE product.
