内蒙胜利褐煤腐殖酸对煤平衡复吸水的影响
Effect of humic acid on equilibrium adsorption of water of Shengli lignite
摘要
Abstract
The effect of humic acid, an important component of lignite, on the water content in Shengli lignite was studied. The content of oxygen containing functional groups of humic acid in Shengli lignite was determined. The isothermal adsorption and desorption curves of the lignite, brown humic acid and the residual coal were analyzed. Further the primary and secondary site adsorption of the lignite, brown humic acid and the residual coal were studied. The results show that 2/5 carboxyl and 1/5 hydroxyl in Shengli lignite are provided by humic acid. The pore size and pore volume of brown humic acid are smaller than those of the lignite. So brown humic acid is unfavorable for the formation of water clusters. The humic acid is adverse to equilibrium adsorption of water for Shengli lignite.关键词
