  • Process for increasing meso phase contents in pitch
    Patent number: 4976845
    Abstract: A process for increasing the content of mesophase in a pitch includes using a high molecular aromatic fraction based on a material selected from the group consisting of coal tar, crude oil and their mixture in molten form, thermally treating the fraction in form of a thin, continously moving film, and removing volatile components by degassing during the thermal treatment. The process distinguishes in using a high molecular aromatic fraction which may contain mesophase, shaping the fraction continuously mechanically to a thin film with a layer of thickness of between substantially 0.
