On the 23rd of that month, an expert review meeting for the \"Feasibility Study Report on the High-Value Utilization of Coal-Based Ethanol to Produce Polyols\" was held in Xi’an by Yushen Energy Chemical Company of Shaanxi Yanchang Petroleum. This marked the successful completion of a key review stage for this feasibility study report, laying a solid foundation for the further advancement of the project. It is reported that this project is an upgrade initiative for the downstream sector of Yushen Energy Chemical’s 500,000 tons per year coal-based ethanol production facility; by utilizing the ethanol produced locally as the main raw material, it aims to gradually expand production to 30,000 tons per year of acetaldehyde and 10,000 tons per year of 1,3-butanediol, which are high-value products. After the implementation of the project, it will not only enhance the overall competitiveness and risk resistance of the enterprise as well as help identify new sources of profit growth, but it will also spur the development of related industries, contribute to the optimization of the employment structure, and achieve a synergistic benefit in terms of economic, environmental, and social outcomes. The total investment in Yushen’s 500,000 tons per year coal-based ethanol project operated by Yanchang Petroleum is 6.98 billion yuan. Using coal as a raw material, methanol is synthesized through coal gasification, and then anhydrous ethanol and other chemical products are produced via dehydration, carbonylation, and hydrogenation processes. The project utilizes a technology for producing ethanol through dimethyl ether carbonylation, which was jointly developed by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Yanchang Petroleum and holds independent intellectual property rights. Construction of this project began in June 2020, and it was completed and put into use on June 30, 2022 ； In 2023, the 500,000 tons per year coal-based ethanol project of Yanchang Yushen Energy Chemical Company was completed and put into operation.
