借助棒状薄层色谱/氢火焰(TLC/FID)、核磁共振(1H-NMR)以及凝胶渗透色谱(GPC), 对兖州煤与石家庄减压渣油单独处理及其共处理所得的甲苯可溶重质产物的组成、结构和分子量进行了研究, 得到了重质产物的组成性质随反应条件的变化规律. 结果表明, 共处理重质产物的组成性质并非煤与渣油各自加氢处理所得重质产物的简单物理混合, 而是在二者之间发生了化学反应, 说明通过共处理反应可从分子水平调配重质产物的组成性质, 为重质产物的优化利用提供了理论基础.

The characteristics of heavy toluene soluble fractions (HTSF) from coprocessing of Yanzhou coal with Shijiazhuang vacuum resid (SVR) was studied using thin layer chromatography (TLC), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The results showed that strong interaction between the coal and the resid took place in coprocessing. With increasing the reaction severity, the yield of asphaltenes increased, while the yield of saturates and resins decreased. The aromaticity of the HTSF increased and the average molecular weight decreased with increasing the temperature.
