Abstract
A process for producing mesophase pitch, the process including: providing a feedstock having a T5≥400° F. (204° C.) and a T95≤1,400° F. (760° C.); heating the feedstock at a temperature of at least 450° C. to produce a heat treated product including mesophase pitch, wherein the heating is conducted under reaction conditions sufficient to have an equivalent reaction time greater than or equal to 1,000 seconds; and recovering the mesophase pitch.
