摘　　要：褐煤由于水分高、挥发分高、热值低、易自燃,常用作坑口电站燃料。相对于褐煤燃料化利用,提取腐植酸是一种具有较好应用前景的低碳利用途径。在介绍腐植酸提取原料的基础上,对腐植酸提取方法进行了总结,重点对褐煤腐植酸的提取研究进展进行了综述,为促进褐煤及褐煤腐植酸的高值化利用、实现“碳达峰、碳中和”目标提供了帮助。Lignite is often used as fuel for pithead power plants due to its high moisture content,high volatile matter,low calorific value,and easy spontaneous combustion.Compared to the fuel-grade utilization of conventional lignite,extracting humic acid is a low-carbon utilization pathway with good application prospects.On the basis of introducing the raw materials for humic acid extraction,we summarize the extraction methods of humic acid,focusing on the research progress in extraction of humic acid from lignite.This review provides assistance in promoting the high-value utilization of lignite and lignite humic acid,and in achieving the goals of″carbon peak and carbon neutrality″.
