Industry research and development of new technologies for polyolefin products

From November 7th to 9th, the Polyolefin Industry Innovation Alliance, Shanghai Jupu New Material Technology Co., Ltd. and Xi'an Petroleum University jointly hosted the 2018 4th China Polyolefins Conference and the first polyolefin special materials development summit held in Xi'an, from Poly Experts, scholars and business representatives from the olefins industry, in-depth analysis of the development of olefin polymerization catalysts, polyolefin new product development, device intelligence and other cutting-edge technologies. Li Hua, vice president of Xi'an Petroleum University, attended the opening ceremony and delivered a speech.

The olefin polymerization-supported Ziegler-Natta (ZN) catalyst has high catalytic activity, is not sensitive to impurities, has relatively good stability, and is suitable for various polymerization processes, which is beneficial to the long-term stable and continuous production operation of the device. The catalyst cost is low and relatively easy to prepare. At present, there are many domestic development and utilization, but there is still a gap compared with the world advanced level. 'Zhejiang University professor Fan Zhiqiang said that although the olefin polymerization metallocene catalyst develops faster, the supported catalyst has comprehensive performance. Excellent, will continue to occupy a dominant position can not be replaced. Through catalyst optimization and innovation, combined with the optimization of polymerization process, it is expected to achieve more accurate regulation of polyolefin structure and adjustable performance of new generation polyolefin.

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, serialization, customization, integration, characterization and stabilization. Features. Through the introduction of digestion and absorption and independent innovation, we will make fine general materials, enlarge and strengthen special materials, and make thick technical reserves to meet the needs of high-end market.

'Currently, the core original technology of olefin polymerization catalyst and polymerization process is still controlled abroad, which is the main reason why China's high-end polyolefin products need to be imported in large quantities. 'Zhejiang University professor Feng Lianfang told reporters. He shared the olefin slurry polymerization process and its intelligence. The progress and application of reactor technology, it is believed that the liquid phase + gas phase series polymerization technology has both advantages, and the intelligentization of the polymerization process will become a trend, helping the industry to achieve high quality and high efficiency development.

At the meeting, the experts also introduced the progress of olefin polymerization gas phase process and the development of special materials for the end of the cockroach, the construction of new product research and development system, the development of intelligent control and assisted products, and the future development trend of the polyolefin industry.

'This conference aims to promote the benign competition of China's polyolefin industry, enhance exchanges and cooperation, and help the high-end polyolefin industry to differentiate and develop. ' The head of Shanghai Jupu New Material Technology Co., Ltd. said that in recent years, China's polyolefin production is fast. Growth, in 2017, the output of polyethylene and polypropylene reached 14.41 million tons and 20.9 million tons respectively, and the external dependence was 45% and 22% respectively. In the next three years, polypropylene and polyethylene will expand to over 10 million tons respectively. More than 50%, facing the increasingly fierce competition for homogenization, some high-end products rely heavily on imports, and downstream demand is constantly improving.
