一块煤如何裂变多条链——新疆哈密市现代煤化工产业发展调查

Core Viewpoint - Hami City is transforming its traditional energy structure by leveraging its coal resources to develop a modern coal chemical industry, aiming for high-value utilization and low-carbon development while ensuring energy security under the "dual carbon" goals [1][2]. Group 1: Coal Resource Utilization - Hami City is advancing the "coal-to-chemical" industry layout, transitioning from traditional energy output to modern coal chemical production, creating multiple industrial chains from coal [2][3]. - The city has established various industrial chains, including "coal-methanol-carboxylic acid, formaldehyde, polypropylene" and "coal-coke oil-fuel oil" [2]. - Hami's coal chemical industry added value increased by 17.9% year-on-year in the first half of the year [1]. Group 2: Technological Innovation and Projects - Hami is introducing significant projects, such as the world's first second-generation technology for direct coal liquefaction, expected to produce 4 million tons of oil annually by 2027 [3]. - The city is also developing a 1 million tons per year acetic acid project, which is the first of its kind in Xinjiang [4][5]. - Hami's coal-to-chemical projects are designed to maximize resource utilization and reduce environmental impact through advanced technologies [6][7]. Group 3: Circular Economy and Resource Efficiency - Hami is implementing a zero-discharge wastewater treatment project, achieving 100% recycling of industrial wastewater [6]. - The city is focusing on the circular utilization of coal resources, with projects like the 400,000 tons of ethylene glycol from waste gas, maximizing the use of low-value resources [7]. - The comprehensive energy conversion rate of coal processing in Hami exceeds 85%, indicating high efficiency in resource utilization [8]. Group 4: Coupling Development with Renewable Energy - Hami is exploring the coupling of traditional coal energy with renewable energy, with 67.8% of its installed power capacity coming from renewable sources [12]. - New coal chemical projects must source at least 50% of their electricity from green energy, significantly reducing production costs and carbon emissions [12]. - The integration of green hydrogen into coal chemical processes is being promoted, with companies planning to use wind and solar energy to produce hydrogen for chemical production [13][14]. Group 5: Talent and Research Development - Hami is establishing a research institute focused on the clean and efficient utilization of high-oil coal resources, enhancing its research capabilities [11]. - The city is also developing a vocational school to train skilled workers in the energy and chemical sectors, aligning education with industry needs [11]. - Collaborative efforts with universities and research institutions aim to foster innovation in coal chemical technologies [10].
