腐植酸类原料包括泥炭、褐煤和风化煤,其中泥炭和褐煤是煤炭中碳化程度最低或较低的物质。泥炭都在植物能大量繁殖生长的地方不断生长和死亡,其残体在有水的地面,被细菌的作用下逐渐分解,逐渐堆积,逐渐与空气隔绝。进入泥炭化阶段,植物残体继续分解是依靠它本体氧进行厌氧分解、脱水等过程,放出CO_2、CH_4、H_2O等,而生成胶状物质的泥炭,它含有腐植酸、沥青以及一些单酯、半纤维素、纤维素、木质素等,还保持一些植物的原态,如根茎、叶枝、树皮等。
Humic acid feedstocks include peat, lignite and weathered coal, of which peat and lignite are the ones with the lowest degree of carbonization in the coal. Peat grows and dies in places where plants can multiply and grow. The remains are gradually decomposed and accumulate under the action of bacteria in the watery ground, and are gradually separated from the air. Enter the stage of peat, continue to decompose plant residues is relying on its bulk oxygen anaerobic decomposition, dehydration and other processes, emit CO_2, CH_4, H_2O, etc., and the formation of colloidal peat, which contains humic acid, asphalt and some monoester , Hemicellulose, cellulose, lignin, etc., but also to maintain the original state of some plants, such as rhizomes, leaf branches, bark and so on.
