分子煤化学与煤衍生物的定向转化

RELATIONSHIP BETWEEN MOLECULAR COAL CHEMISTRY AND DIRECTIONAL CONVERSION OF COAL DERIVATIVES

从煤中获取“特异化学品”是煤炭非燃料利用的重要途径 .对煤大分子进行“剪裁”,获取“特异化学品”和对这些“特异化学品”进行“缝制”是分子煤化学的两个重要内容 .总结了煤衍生物的种类及它们可以获取的高附加值产品 ,分析了煤衍生物定向转化的合理途径 ,指出了煤衍生物定向转化中存在的问题 。

It is important for non fuel utilization of coal to prepare special chemicals from coal. Clipping coal macromolecule to prepare special chemicals and sewing them are two important aspects of molecular coal chemistry. The paper reviews the coal derivatives and some valuable products from them, and analyzes the reasonable approach to directional coal conversion. Problems in the conversion of coal derivative are pointed out and corresponding solutions are put forward.
