交联的三维大分子模型已被广泛接受的煤的结构，但没有直接的证据来证明这个模型。由于烟煤中相对较强的分子内和分子间相互作用的重要性，本文对传统的煤结构模型进行了重新研究。这是合理的推断，显着的部分是物理关联的多步提取，缔合平衡，不可逆性和煤浓度对溶剂溶胀的依赖性，并考虑单相概念的研究后。在此基础上，对煤液化预处理进行了研究。
A cross-linked, three-dimensional macromolecular model has been widely accepted for the structure of coal, but there is no direct evidence to prove this model. In this paper, the conventional coal structure model is reinvestigated because of the importance of relatively strong intra- and intermolecular interactions in bituminous coal. It is reasonable to deduce that significant portions are physically associated after a study of multistep extractions, associative equilibria, the irreversibility and the dependence of coal concentration on solvent swelling, and consideration of the monophase concept. A pretreatment in coal liquefaction is also investigated on the basis of this proposed concept.
