摘要

与其他化石资源相比，煤富含芳环，特别是缩合芳环，是获取诸多芳香族化合物纯品，特别是诸多具有十分重要用途因而附加值极高的缩合芳香族化合物纯品的非常重要的原料。以所得纯品为原料可以合成一系列高端功能性大分子和聚合物，形成强有力推进我国高质量发展的产业链。然而，煤的组成结构的复杂性使以煤为原料高效获取芳香族化合物纯品面临巨大的挑战。面对此挑战，关键步骤之一是应尽可能地从分子水平上了解煤中有机质的组成结构特征，在此基础上精准裁剪煤中有机质高收率地获得组成比较简单的富集缩合芳香族化合物的可溶有机混合物，而精准裁剪煤中有机质的“利剪”是适宜的高活性催化剂与分子氢作用产生的高浓度活性氢；另一关键步骤是精细分离所得可溶有机混合物尽可能高收率地获取有机化合物，特别是缩合芳香族化合物纯品。基于作者的前期研究工作，本文重点阐述如何应对煤炭资源高值化利用面临的挑战，包括如何了解煤中有机质的组成结构特征、如何精准裁剪煤中有机质和如何精细分离所得可溶有机混合物。本文还从国家高质量发展的角度展望了煤炭资源高值化利用的发展前景。

Abstract

Compared to other fossil resources

coals are more rich in aromatic rings

especially condensed aromatic rings

and are thereby very important raw materials for obtaining many pure aromatics

especially pure condensed aromatics

which have many very important applications and are hence highly value-added. A series of advanced functional macromolecular species and polymers can be synthesized to form an industrial chain for strongly promoting the high-quality development of our country. However

using coals as raw materials to efficiently obtain the pure aromatics faces huge challenges due to the complex compositional structures of coals. Facing the challenges

one of the crucial steps is to understand the compositional and structural features of organic matter in coals at the molecular level

and based on the understanding

soluble organic mixtures which are rich in condensed aromatics with relatively simpler composition could be obtained in high yields by precisely cutting the organic matter in coals

while the “sharp scissors” to precisely cut the organic matter in coals are high concentration of active hydrogen species formed by the interaction of molecular hydrogen with highly active catalysts. Another crucial step is to elaboratively separate the resulting soluble organic mixtures to obtain pure organic compounds

especially pure condensed aromatics in high yields. Based on our previous work

this paper focuses on how to meet the challenges faced on the value-added utilizations of coal resources

including how to understand the compositional and structural features of organic matter in coals

how to precisely cut the organic matter and how to elaboratively separate the resulting soluble organic mixtures. In this paper

the development prospects for the value-added utilizations of coal resources are also outlooked in terms of the high-quality development of our country.
