Abstract
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.
