China Drying Network News Recently, the 20,000 tons/year 1-hexene plant basic design project of the Dushanzi Petrochemical Company, undertaken by the PetroChina Research Institute of Petroleum and Petrochemicals, passed the technical review organized by the Science and Technology Management Department of the China National Petroleum Corporation. The construction of the device officially started. 1-hexene is an important comonomer for the production of high-performance polyethylene resins. The 1-hexene-modified copolymer polyethylene has excellent tensile strength, tear strength, transparency, and resistance to environmental stress cracking. After more than 20 years of continuous research and development of the 1-hexene pilot technology for catalyst, process, and reactor integration, the PetroChina Research Institute of Petroleum and Petrochemical Technology has established a 5000-ton/year industrial test facility at Daqing Petrochemical to produce a purity of 99%. High-quality 1-hexene products, the main technical indicators are better than similar foreign technology. The 20,000-ton/year 1-hexene technology package developed on this basis will provide technical support for the construction of a 20,000 tons/year 1-hexene production facility for Dushanzi Petrochemical Company.
