摘要
煤沥青具有碳含量高,芳香度高等特点,是重要的炭材料合成前驱体。但由于沥青结构组成复杂,并不能用单独一、两种分析技术明确解释其组成结构,往往采用多种分析技术结合来解析煤沥青的组成结构。本文阐述了国内近年来在煤沥青的分析中应用最为广泛的分析仪器与技术,综述了不同分析表征技术对煤沥青性质的描述和解析。
Coal tar pitch has high carbon content and aromaticity. It is an important precursor to produce carbon materials. The complex structure can not be explained clearly by a single analytical method. More analytical techniques are often used to analyze coal tar pitch. In this paper, the widely used analytical instruments and techniques for coal tar pitch are described in recent years,such as chromatography. The applications of different analysis techniques in coal tar pitch are summarized in this paper.
