摘要：
A method of making a mesophase pitch comprising: feeding a coal tar pitch having a softening point in the range of about 70°C to 160°C into a processing vessel, wherein the processing vessel is heated to a temperature in the range of about 300°C to 450°C and wherein the pressure inside the processing vessel is 5 Torr or less; obtaining a distillate from said processing vessel, said distillate having a softening point in the range of about 40°C to 80°C and being quinoline insoluble free and ash free; heat treating said distillate at a temperature range of 400°C to 455°C for between 3 and 8 hours.
