Abstract：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.
