Sinopec’s polypropylene process technology exported to the United States Recently, Sinopec signed a technology licensing agreement for the “gas-phase polypropylene continuous prepolymerization technology” with Formosa Plastics USA. This technology thus became Sinopec’s first polypropylene process technology exported to the United States. 　　Over the years, the Beijing Research Institute of Chemical Technology has implemented an innovation strategy centered around the core business of the group company, and by leveraging its platforms for physical analysis and characterization of polymers, it has made significant progress in polyolefin catalyst technology, polymerization process technology, and the development of new polyolefin products. In terms of polyolefin catalysts, BCE catalysts and DQ-HA catalysts, which are at the international leading level, have been developed and are now in large-scale industrial use as well as being exported abroad. In terms of olefin polymerization process technologies, continuous prepolymerization technology for gas-phase polypropylene and high-temperature gas-phase polypropylene processes have been developed and have entered the stage of large-scale industrial application. In the development of new polyolefin products, high-value-added products such as G® resin, high-melt-strength polypropylene, and high-purity polypropylene have been successfully developed and brought into industrial production. 　　“The \"Gas-phase Polypropylene Continuous Prepolymerization Technology\" is an efficient, green, and low-cost polypropylene production process developed over many years by the Beijing Institute of Chemical Technology. It enables effective improvement in catalyst activity, suppression of temperature fluctuations in the reactor bed, reduction of caking and fine powder formation, and extension of the plant’s operational cycle. Additionally, it significantly reduces the amount of hexane used, lowers the content of volatile organic compounds in the polypropylene product, and cuts down on the operating costs of the plant. As of the first half of this year, this technology has been licensed for 4 sets in China.
