On August 20th, amid the roar of machinery, the AA-grade methanol distillation phase of the first stage of Phase II of Shaanxi Coal Group Yulin Chemical Co., Ltd.’s 15-million-ton-per-year demonstration project for the clean and efficient conversion of coal into various products was officially launched. This commencement marks not only a significant breakthrough for the Sixth Branch in the Shaanxi Coal Yulin Chemical series of projects, but also an active effort by the branch to respond to the **\"dual carbon\" strategy and advance progress in green energy chemistry. The 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products by Shaanxi Coal Group Yulin Chemical Co., Ltd. is currently the coal chemical project with the largest single-investment amount. The total investment in the chemical manufacturing facilities amounts to 176 billion yuan. Building on the first phase of the project, this initiative relies on coal pyrolysis, coal tar hydrogenation, and pulverized coke gasification technologies as key elements. By integrating these technologies along with downstream processing methods, it aims to further expand and extend the industrial chain, and to explore new approaches for the simultaneous development of coal-based olefins and coal-based aromatics. The end product will be a range of chemical substances such as polyolefins, polyesters, polycarbonates, polyether polyols, EVA, POE, SAP, DMC, DEC, EMC, and EC. It is expected that the annual sales revenue will exceed 90 billion yuan. 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 by Shaanxi Coal Group Yulin Chemical Co., Ltd. covers an area of approximately 9,200 mu, with an estimated total investment of around 62 billion yuan. Upon completion of the project, it is expected to generate annual sales revenue of 20.7 billion yuan and after-tax profits of 3.3 billion yuan. This project was included in the **13th Five-Year Plan for Energy Development** and the **13th Five-Year Plan for Demonstration of Advanced Coal Processing Industries**, and is to be constructed in two phases. Phase 1 has already seen the construction of an ethylene glycol plant with a capacity of 1.8 million tons per year and a coal pyrolysis plant with a capacity of 1.2 million tons per year; a DMC plant with a capacity of 500,000 tons per year is currently under construction ； The second phase of the plan involves the construction of facilities for the production of olefins, aromatics, and products derived from their further processing. By making efficient use of coal through proper sorting and classification, this project will produce key platform products such as olefins, aromatics, and base oils. Further processing will then enable the production of four categories of end products with high added value: advanced materials, battery electrolyte solvents, biodegradable materials, and special types of oils, thereby achieving coordinated development between coal chemical industry and petroleum chemical industry. The second phase of the 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products by Shaanxi Coal Group Yulin Chemical Co., Ltd. will build upon the infrastructure established in the first phase to further extend the industrial chain. Following a strategy focused on high-end development, diversification, and low carbon emissions, this project aims to produce more than 30 different end products in four main categories: high-value materials, battery electrolyte solvents, biodegradable materials, and special oils. Meanwhile, this project has received significant attention from the provincial Party committee and government; it has also been included in the key projects for the 14th Five-Year Plan in Shaanxi Province and Yulin City. To date, the project has obtained 19 important preliminary approvals, including environmental impact assessments, approvals, and water extraction permits. The second-phase project is constructed in two stages; the first stage focuses on the construction of gasification, methanol synthesis, methanol-to-olefins, and related downstream olefin processing units ； In the second phase, facilities for coal pyrolysis, tar hydrogenation, arene synthesis, biodegradable materials, and battery electrolytes will be primarily constructed.
