  • Ultra purified pitch process
    Patent number: 11655418
    Abstract: A process for producing isotropic and mesophase pitch with reduced solids contamination from aromatic liquids contaminated with solids, such as catalyst fines or semi-coke. Contaminated feed is charged through one or more pitch forming reactors which discharge a pitch rich liquid and a vapor phase with reduced solids contamination. The vapor phase is cooled, condensed and may be charged continuously to another pitch forming reactor in parallel or used intermittently as a total or partial replacement for solids contaminated feed.
