对褐煤在氧化反应制备化学品、腐植酸制备以及功能碳材料制备方面的研究进展进行了综述。尽管褐煤的非能源化利用丰富了褐煤的利用方式，提高了褐煤利用的经济附加值，但仍存在反应条件不够温和、产物分离困难、转化率低等问题。因此，进一步研究褐煤的结构组成，并针对褐煤不同组分的结构和反应特性开展相关的应用研究，将对提高褐煤非能源化利用的效率具有重要意义。

This paper reviews the research progress in non-energy utilizations of lignite,such as in the preparation of chemicals by oxidation,humic acid and functional carbon materials.Although the non-energy utilization can enrich the utilization model of lignite and increase remarkably economic added value of lignite,there still exist problems of strict operation conditions,difficult in products separating and low conversion rate.Therefore,further researches on structure and composition of lignite are needed.The related application researches developed according to the structure and reaction characteristics of lignite with different components will play an important role in improving the efficiency of non-energy utilization of lignite.
