On November 26, significant progress was made in the first phase of the second stage of the 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products, carried out by Shaanxi Coal Group Yulin Chemical Co., Ltd.: the concrete pouring for the third layer of the frameworks for units 1 and 2 was completed successfully. The successful completion of this node has laid a solid foundation for the subsequent construction of the main structure, effectively securing control over the project timeline. At present, the project has fully entered the critical phase of winter construction. The first phase of the second phase of the Shaanxi Coal Yulin Chemical project utilizes space furnace gasification to produce 5.6 million tons per year of methanol, 1.5 million tons per year of methanol-to-olefins products, 300,000 tons per year of polyethylene (FDPE), and 300,000 tons per year of polypropylene (PP). The 15 million tons per year demonstration project for the clean and efficient conversion of coal based on differentiated quality categories, operated by Shaanxi Coal Group Yulin Chemical Co., Ltd., makes full use of the abundant coal resources in the Yulin area. With \"technology for the differentiated use of coal\" as its core, it combines modern coal chemical processes with various compounds from petroleum chemistry through two pathways: coal-to-olefins and coal-to-aromatics. This approach extends the industrial chain, resulting in the production of 45 different products across 4 categories, including high-value-added materials, biodegradable materials, battery electrolyte solvents, and special oils. Once the project is fully completed, it is expected to generate annual sales revenue of 134 billion yuan, annual profits of over 30 billion yuan, and create more than 7,000 job opportunities.
