Abstract (en)
[origin: WO2022015281A1] A process for making mesophase and/or isotropic pitch. An aromatic rich liquid is charged at high temperature and pressure to a first thermal polymerization reactor to produce an isotropic pitch rich liquid which is flashed. Residual liquid is charged to a second thermal reactor to produce mesophase pitch. The reactors can be either tubular reactors or CSTRs. Carbonized or graphitized fibers, foams, blocks, sheets or spheres may be produced from the mesophase pitch.
