摘要
针对传统化工生产过程中对褐煤脱水方式的不同,因热压、非极性有机溶剂四氢化萘的作用,将导致褐煤的物理和化学结构发生明显变化。因此从实验的角度对两种不同脱水方式下褐煤结构变化进行分析,从而更加深刻地认识到这两种脱水方式的特点,以便于在今后的生产中选择合适的脱水方式。
In view of the difference in dehydration methods of lignite in the traditional chemical production process,the physical and chemical structure of lignite will change significantly due to the effect of hot-pressing and non-polar organic solvent tetralin.This article analyzes the structural changes of lignite under two different dehydration methods from the perspective of experiment,and thus realizes the characteristics of these two dehydration methods more profoundly,so as to select the appropriate dehydration method in the future production.
