It is understood that 1-hexene is an important comonomer for the production of high-performance high-density polyethylene and linear low-density polyethylene. Polyethylene resin obtained from its products has the advantages of high tensile strength, impact resistance and tear resistance, and is particularly suitable for the production of packaging films and agricultural cover films, as well as the manufacture of advanced lubricating oils, plasticizers, and surface actives. Agents and other important raw materials for fine chemical products. However, because there is no industrialized production equipment of 1-hexene production technology for ethylene trimerization at present, 1-hexene can only rely on high-price imports for a long time, which has affected the upgrading of polyethylene products in China. Therefore, the construction of this device is of great significance for improving the grade of China's polyethylene products and enhancing market competitiveness.
Over the years, Yanshan Petrochemical has been committed to the research and development of the ethylene trimerization 1-hexene process technology with independent intellectual property rights and the pilot application of pilot plants. Based on the completion of the small-scale test and model test study, the company completed a 500-tonne/year ethylene trimerization 1-hexene pilot plant in July 2002. Accumulative operation data for more than 2,000 hours indicate that 1-hexene products The purity is greater than 98%, the selectivity is greater than or equal to 93%, there is no special environmental protection issue, and the overall technology reaches the international advanced level. The gas-phase polyethylene test and the 120,000-ton/year polyethylene industrial plant application, the quality of 1-hexene completely meets the quality requirements of ethylene comonomer. On this basis, Yanshan Petrochemical completed the preparation of a 50,000-ton ethylene-trimethylene 1-hexene complete technology package, and at the end of May 2004 passed the identification and review of the organization of Sinopec Joint Stock Company.
The first domestic 50,000-ton/year 1-hexene industrialized production facility broke ground at Yanshan Petrochemical. The device uses Yanshan Petrochemical's own research and development of ethylene trimerization 1-hexene process technology, and is expected to be completed and put into operation by the end of the year.
