November 7-9, the Polyolefin Industry Innovation Alliance, Shanghai Polypu New Materials Technology Co., Ltd. and Xi'an Petroleum University jointly hosted the 4th China Polyolefin Conference and the first Polyolefin Special Materials Development Summit held in Xi'an, experts, scholars and business representatives from the polyolefin industry, around the development trend of olefin polymerization catalysts, new product development of polyolefins, intelligent devices and other cutting-edge technology in-depth discussion and exchange. Li Hua, Vice President of Xi'an Petroleum University, attended the opening ceremony and delivered a speech

" olefin polymerized load type Ziegler-Nata (Z-N) catalyst catalytic activity is high, not sensitive to impurities, relatively good stability, adapted to a variety of polymerization processes, conducive to the installation of long-cycle stable continuous production and operation. At the same time, the catalyst is low cost and relatively easy to prepare. At present, there is more domestic development and utilization, but compared with the world's advanced level, there is still a gap. Fan Zhiqiang, a professor at Zhejiang University, said that although olefin polymerized metal catalysts are developing rapidly, load-type catalysts will continue to dominate because of their excellent overall performance. Through catalyst optimization and innovation, combined with the optimization of polymerization reaction process, it is expected to achieve more accurate regulation of polyolefin structure and the performance of the next generation of polyolefins adjustable.
Liu Bo, former president of Sinopec Yangzi Petrochemical Research Institute, said that the development of new polyolefin products is a systematic project involving process, equipment, control and other aspects, showing marketization, series, customization, integration, characteristics and stability. Through the introduction of digestion and absorption and independent innovation, to do fine general materials, bigger and stronger special materials, thick technical reserves, to meet the high-end market demand.
"At present, the core original technology of olefin polymerization catalyst and polymerization process is still controlled by foreign countries, which is the main reason why China's high-end polyolefin products need to be imported in large quantities." Feng Lianfang, a professor at Zhejiang University, told reporters. He shared the progress and application case of olefin silting polymerization process and its intelligent reactor technology, and believed that the liquid phase-gas concatenation polymerization technology has both advantages, while the polymerization process intelligence will become a trend, helping the industry to achieve high-quality, high-efficiency development.
meeting, the relevant experts also introduced the progress of the olefin polymer gas phase process and the development of special materials at the end of the oleum, the construction of new product research and development system, intelligent control to assist product development, and look forward to the future development trend of the polyolefin industry.
"The conference aims to promote the sound competition of China's polyolefin industry, enhance exchanges and cooperation, and promote the high-end and differentiated development of the polyolefin industry." Shanghai Polypu New Materials Technology Co., Ltd. said that in recent years, China's polyolefin production has grown rapidly, in 2017 polyethylene, polypropylene production reached 14.41 million tons and 20.9 million tons, respectively, the external dependence of 45%, 22%. In the next 3 years, polypropylene and polyethylene will expand production by more than 10 million tons, a growth rate of more than 50%, facing the increasingly fierce homogenization competition, some high-end products rely heavily on imports, downstream requirements continue to improve the situation.
