[Abstract]:Mesophase pitch was prepared by one-step hydrogenation-polymerization treatment on the liquefaction residue of Shenhua coal. The composition and structure of asphalt products were studied by means of elemental analysis, IR, NMR and so on. The appropriate technological parameters were determined to provide guidance for industrial production. The effects of tetralin addition and reaction temperature on the yield and morphology of mesophase pitch were investigated. It was found that the ratio of liquefied residue to tetralin was 3: 1 at 380 鈩，
