煤油共液化残渣制备中间相沥青及其表征
Preparation and Characterization of Mesophase Pitch from Coal and Oil Slurry Coliquefaction Residue
摘要
Abstract
In this study ,mesophase pitch was synthesized from two kinds of refined asphalt‐ene (A1 ,A2) extracted from Yanzhou coal and fluidized catalytic cracking slurry (FCCS) coliq‐uefaction residue (CLR1 ,CLR2) by pyrocondensation method at atmospheric pressure .Me‐sophase pitch was characterized by polarized optical microscopy (MOP) ,Fourier transform infra‐red spectrometry (FT‐IR) and scanning electron microscopy (SEM ) .The results show that A1 and A2 generated mesophase microspheres w hen hold at 380 ℃ for 10 h ,A1 sample formed ani‐sotropy flow domain when hold at 440 ℃ for 6 h ,while A2 sample formed bulk anisotropy me‐sophase when hold at 440 ℃ for 12 h .In addition ,the content of TI and QI of the mesophase pitch samples increased with the increase of temperature and holding time ,but the yield decreased contrarily .Research suggests that mesophase microbeads and needle coke could be produced from asphaltene of coliquefaction residue .关键词
