Patent number: 11319491Abstract: 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 effluent stream which is flashed to remove unconverted or partially converted feed as a vapor yielding a liquid phase enriched in isotropic pitch. The enriched isotropic pitch liquid is charged to a second thermal reactor and reactor effluent flashed to produce mesophase pitch and a vapor phase. The vapor phases from both flashing steps are condensed and combined for recycle of a liquid aromatic rich stream to the first reactor. Flashing from the first reactor cools the liquid phase which is enriched in isotropic pitch. This enriched stream is mixed with a superheated fluid, preferably steam, upstream of the second reactor.Type: GrantFiled: May 22, 2020Date of Patent: May 3, 2022Inventors: Thomas C Holcombe, David C Boyer
