On December 12, 2024, the Cangzhou Lingang Economic and Technological Development Zone issued a notice announcing the second round of public disclosure of information regarding the environmental impact assessment for the first phase of Hebei Siyoushu Carbon New Materials Co., Ltd.’s project aimed at producing 100,000 tons per year of α-olefins. According to the environmental impact assessment, the company’s 745,000 tons per year integrated project for new tertiary carbon materials (Phase I) was approved on October 21, 2022, and is currently under construction. To seize market opportunities, the company plans to invest 400 million yuan in the implementation of the \"Phase I project of Hebei Siyoushu Carbon New Materials Co., Ltd., with an annual production capacity of 100,000 tons of α-olefins.\" This project will involve the construction of one set of α-olefin production facilities along with related auxiliary systems; once completed, it will enable an annual production of 100,000 tons of α-olefins. Based on the products manufactured, the main products of this project are α-olefins – high-carbon nonene and dodecene. The main products of this project are α-olefins – high-carbon nonene and dodecene. Nonene is primarily used in the production of products such as decanol, nonylphenol, and neodecanoic acid, and it is also employed in the manufacture of plasticizers, surfactants, coating components, paint drying agents, and polymer modification agents. ExxonMobil, Shell, Braskem, etc. are currently the main players in nonene. Hebei Xinxinyuan is the largest producer of nonene products in China, holding a market share of over 75% in the domestic market. Dodecene, also known as tetrapropylene, is an isomer of triisobutylene; it is a colorless liquid that is soluble in alcohol, ether, acetone, and petroleum ether, but insoluble in water. It is mainly used in the production of products such as acrylonitrile butadiene styrene, styrene-butadiene rubber, styrene-butadiene latex, tert-dodecyl mercaptan, and linear or branched alkylbenzenes. Approval granted for 300,000-ton α-olefin project: On August 29, 2023, the Hebei Province Online Approval and Supervision Platform for Investment Projects showed that the Hebei Provincial Development and Reform Commission had approved the first phase of the project, with an annual production capacity of 100,000 tons of α-olefins, as well as the second phase, with an annual production capacity of 200,000 tons of α-olefins (along with the construction of a 360,000-ton internal alkanes dehydrogenation unit). The approval process involved the registration of hazardous chemical processes that are under strict supervision, hazardous chemicals that require close monitoring, and major hazard sources. Construction unit: Hebei Siyou Shucarbon New Materials Co., Ltd. Project location: The project is situated in the Cangzhou Lingang Economic and Technological Development Zone, covering an area of approximately 220 mu. Investment amount: Total investment of 1,890.43 million yuan. Construction content: Phase I project with an annual production capacity of 100,000 tons of α-olefins ； The second phase of the project, with an annual production capacity of 200,000 tons of α-olefins (accompanied by a 360,000-ton propane dehydrogenation unit), as well as the associated storage and transportation tanks for raw materials and products, and loading/unloading facilities. Related supporting control buildings, as well as public utility systems such as fire protection, circulating water, power transformation and distribution, water treatment, and auxiliary production facilities. In the first phase, oligoolefins are produced from propylene; in the second phase, propylene is generated through propane dehydrogenation, which is then used to produce oligoolefins.
