中国泥炭褐煤资源及发展腐植酸钾产业潜力

Peat and brown coal resources in China and its potential for developing potassium humate fertilizer

泥炭、褐煤含有丰富的腐植酸,是世界各国规模化生产腐植酸产品的主要资源。针对中国煤炭腐植酸资源开发粗放、技术水平落后、资源浪费严重的现实问题,评述了国内腐植酸行业的特点及发展高附加值腐植酸产品的潜力方向。首先介绍了国内主要煤炭腐植酸资源泥炭和褐煤的分布特征及成分特点。其次综述了腐植酸产品的主要加工工艺和其在工农业各领域的国内应用现状。最后基于国情,从国内农业肥料的未来发展方向及腐植酸的应用潜力出发,提出并评价了腐植酸高附加值利用的未来发展方向之一,腐植酸钾肥的发展潜力。

Peat and brown coal are the main resources of humic acid all over the world. In this paper, we describe a potential way for development of potassium humate with humic acid based on the fact that the existing humic acid industry in China is at a lower production level with serious waste of resources, etc. The distribution and characteristics of peat and brown coal resources in China are introduced first, and then the main processing methods of humic acid as well as its application in agriculture and industries are summarized in detail. Finally, we propose one possible high value utilization way of humic acid to develop potassium humate fertilizer, which is appropriate to the future development of China＇s fertilizer industry and humic acid industry.
