专家把脉榆林煤化工转型方向

Core Viewpoint - The article emphasizes the need for Yulin to leverage its unique resource advantages to achieve multi-energy integration and extend the industrial chain, particularly in the fine chemical industry, to build a distinctive energy strategic system [2][3]. Industry Development - Yulin is recognized as a national-level energy and chemical base, being a significant production hub for methanol, coal-to-olefins, and polyvinyl chloride, with leading production capacities [2]. - The region has established a modern coal chemical industry system comprising four trillion-level and eight hundred-billion-level projects, supported by fine chemical initiatives [2]. Resource Utilization - Yulin possesses a comprehensive resource base, including coal, oil, gas, and salt, which should be utilized to promote the coupling of coal chemical and traditional petrochemical industries, as well as the integration of renewable and fossil energy [3]. - The collaboration between Dalian Institute of Chemical Physics and China Shenhua Coal to Oil Chemical Co. has led to the development of a new technology for producing 1,2-dichloroethane from ethylene glycol and methane chlorides, addressing high energy consumption and emissions issues associated with traditional methods [3]. Environmental Impact - The introduction of green hydrogen in coal-to-olefins processes can replace traditional water-gas shift reactions, reducing CO2 emissions by 70% [4]. - The oxygen produced from water electrolysis can be utilized in coal gasification processes, contributing to a zero-carbon or even negative carbon footprint for coal chemical production [4]. Innovation and Collaboration - The establishment of a deep integration platform for production, education, research, and application in fine chemicals is recommended to focus on high-end fine chemical products and functional materials [4].
