煤气化灰渣资源化综合利用研究进展

摘要

在“双碳”战略纵深推进与循环经济全面转型的背景下,我国煤气化灰渣年排放量已超8000万吨,巨量固废的堆存处置带来严峻的环境风险与资源浪费,其规模化、高值化利用已成为煤化工行业绿色低碳转型的核心命题。本文系统阐述了煤气化灰渣的形成机制与理化特性,梳理了其在掺烧热利用、建材化消纳、生态修复、高值材料制备四大领域的研究与应用进展,剖析了碳灰分离核心技术的原理与应用瓶颈。结合《循环经济发展“十五五”规划》、《固体废物污染防治“十五五”规划》等最新政策导向,文章提出应以“减量化、资源化、高值化”为统领,构建“依质定向、分级利用、全链协同”的资源化利用体系,并针对行业现存问题展望了未来发展方向。
