摘要
简述了煤中有机硫结构的基本概念及对其研究的重要意义,总结煤中有机硫结构的类型主要有硫醇、硫化物和二硫化物、噻吩、亚砜和砜等,并归纳了常用的研究方法。详细阐述了煤抽提物及全煤中有机硫结构的研究现状,叙述了显微组分和超高有机硫煤中有机硫的分布。讨论了煤中有机硫结构的形成和演化,指出目前研究中存在的主要问题并针对性地提出今后一段时间关于煤中有机硫结构的研究趋势。
The concept of organic sulfur structure in coal( OSSC) and its research significance are briefly introduced.The main types of OSSC include thiol,sulfide / disulphide,thiophene,sulfoxide and sulfone. The research methods frequently used are generalized,and the recent development in the study on organic sulfur structure in coal extract and whole coal,and the distribution of organic sulfur in macerals and super-high-organic-sulfur coals are elaborated in detail. In addition,the formation and evolution of organic sulfur compounds are discussed,and the primary problems and research trends of the study on OSSC are also proposed.
