7. The butyl acetate project of Weijiao Group: On July 12, an event marking the completion of key projects in Zaozhuang City was held via video conference. Before the meeting, Zhang Hongwei, Secretary of the Municipal Party Committee, and Zhai Jun, Mayor, led the attendees on a site visit to Xuecheng Energy Company’s benzene hydrogenation project. Yang Ming, the company’s executive director, provided a detailed overview of the progress in accelerating the construction, commissioning, and operation of this project. He also gave a brief introduction to the 2×50,000 tons/year anhydride and 100,000 tons/year plasticizer projects that are under construction, as well as the 250,000 tons/year butyl octanol and 180,000 tons/year aniline projects that are in the planning stage, along with the details of the third phase of the railway logistics project. The project was constructed by Xuecheng Energy Co., Ltd. of Shandong Weijiao Group and is located within the Xuecheng Chemical Industry Park. With a total investment of 5 billion yuan, it uses coal, benzene, propylene, and other materials as primary raw materials to build multiple downstream processing units, including one unit for producing butyl octanol at a capacity of 250,000 tons per year and one unit for manufacturing aniline at a capacity of 180,000 tons per year. 8. Rongsheng’s butyl octanol project in Inner Mongolia: On July 3, Rongsheng Energy Technology (Inner Mongolia) Co., Ltd. submitted an application for approval regarding its project for producing butyl octanol and acetates from coal. The total investment for this project is approximately 20.08 billion yuan, with a planned construction period from July 1, 2025, to June 30, 2029. The project will include the construction of gasification units (producing 200,500 tons per year of syngas, 282,100 tons per year of carbon monoxide, and 2,700 tons per year of hydrogen), an acetic acid plant with a capacity of 500,000 tons per year, a vinyl acetate plant with a capacity of 350,000 tons per year, 3 plants for producing ethylene-vinyl acetate copolymer resins/low-density polyethylene resins, each with a capacity of 350,000 tons per year, a butanenol plant with a capacity of 400,000 tons per year, and plants for producing acrylic acid and its esters, with capacities of 300,000/620,000 tons per year, in addition to supporting utilities, storage and transportation facilities, environmental protection systems, and auxiliary production facilities. The project uses coal as raw material, and through a gasification unit, it produces high-quality syngas, CO, and hydrogen. Syngas and hydrogen are used to synthesize butyl octanol products, while CO is used to produce acetic acid products. Acetic acid serves as a raw material for producing vinyl acetate via a vinyl acetate production unit; vinyl acetate is then used to manufacture EVA through an EVA/LDPE production unit. Butyl alcohol and octanol, produced by the butyl octanol unit, are used as raw materials to produce methyl acrylate, butyl acrylate, and octyl acrylate via acrylic acid and esters production units. Focusing on high-end downstream derivative chemical products and new materials, it aims to reduce dependence on imports of high-end chemical products such as EVA, enhance the strategic capacity for producing high-end chemical products from coal as a raw material, and promote the utilization of coal resources in the Inner Mongolia region.
