At the end of September, the 5,000-tonne ethylene oligomerization year for the hexene-1 industrial test facility was established with the independent development of catalyst and process technology by the China Petroleum Institute of Petroleum and Petrochemicals. The Daqing Petrochemical Company successfully launched the vehicle. This hexene-1 has been successfully domesticated, marking that China Petroleum’s polyethylene plant will change to “domestic grainâ€, which will not only promote the upgrading of PetroChina's polyethylene product structure, but also increase the economic efficiency of China Petroleum by more than 30 years each year. Billion yuan.
Polyethylene products made from hexene-1 are superior to ordinary products in terms of tensile strength, right-angled tear strength, and other indicators. They are suitable for packaging films and agricultural films with long service life and high added value. However, due to foreign technology monopoly, China Petroleum's hexene-1 is all dependent on imports, and its price is high.
In order to enhance the competitiveness of polyethylene products in the market, the Petrochemical Institute has worked hard to explore and successfully develop a three-step hexene-1 synthesis process for the Qi-Na system and obtained national invention patents. In response to problems such as low product selectivity and high co-catalyst risk, the Petrochemical Institute started with catalyst innovation and completed high-selectivity hexene-1 pilot study, 100-ton pilot scale amplification, and process package development to form a world advanced system. Horizontal ethylene oligomerization of chromium catalysts for the synthesis of hexene-1 process technology. The main technical and economic indicators of this process technology have reached or surpassed the level of similar foreign technology.
Hexene-1 process technology development has been highly valued by China National Petroleum Corporation and supported by the planning and planning department, the science and technology management department, and the refining and chemical sector. In particular, in 2007, PetroChina innovated the industrialization mechanism of scientific research achievements, making this the first major scientific and technological project of the refining and chemical business, investing over 70 million yuan, and building a 5,000 metric tons hexene-1 industrial test facility in Daqing Petrochemical directly promoting the The industrialization of hexene-1 scientific research results. On September 25 this year, the Hexene-1 industrial test plant was successfully launched to produce hexene-1 with a purity of 99.53%.
