China Drying Network News Recently, news from the Lanzhou Chemical Research Center reported that China Petroleum Research Institute of Petroleum undertakes impact polypropylene copolymer (PP) catalyst pilot test and industrial application of one of the 15 kg / batch of spherical polypropylene catalyst The test equipment was successfully fed once, and a qualified catalyst pilot product (PC-2) was prepared, and 1.5 tons of pilot product that fully meets the T30S quality index was produced. The test results of polypropylene pilot plant evaluation show that the technical indicators of the catalyst all meet the contract requirements, which lays a solid foundation for the large-scale preparation and industrial application of high-performance catalysts in the next step. After many years of painstaking research, the Institute of Petroleum and Petrochemical Engineering of China has comprehensively overcome a series of technical problems, such as the internal electron donor, catalyst loading, spherical magnesium chloride carrier preparation, and the recycling of raw materials for catalyst preparation. It was successfully developed in 2007. Polypropylene catalyst pilot preparation process package with independent intellectual property rights. In March 2011, trials of impact copolymerization polypropylene catalysts and industrial applications were formally initiated at the China Petroleum Technology Management Department. In April 2011, the Research Institute of Petroleum and Chemicals officially commissioned Lanzhou Ryukyu Engineering Co., Ltd. to initiate the design work of a 15 kg/batch spherical polypropylene catalyst for the preparation of pilot plant construction drawings. In March 2012, the project successfully entered the construction phase, and it was delivered in the plant on August 20th. Chemicals were commissioned on November 26, and a spherical polypropylene catalyst was successfully prepared on December 2. On December 27, the evaluation of the pilot polymerization of the catalyst was completed, and a successful pilot production of 1.5 tons of pilot products with the quality that fully meets the T30S requirements. The spherical polypropylene catalyst is a catalyst suitable for Basel's Spheripol propylene polymerization process. At present, the global polypropylene production exceeds 100 million tons, and the production capacity of the Spheripol propylene polymerization process exceeds 50%. In the past, because domestic companies did not master the development technology of high-performance polypropylene catalysts, China had to import a large amount of foreign materials from abroad at a high price every year. Not only was it technically controlled by others, but foreign large companies basically monopolized domestic high-performance and high-value-added technologies because of their technological advantages. Polypropylene market. Polypropylene producers in China are facing bottlenecks in the development of high value-added polypropylene, and they have no say in the high-end market for polypropylene products.
