  • Coal tar and hydrocarbon mixture pitch and the preparation and use thereof
    Patent number: 7465387
    Abstract: A method of making a carbon/graphite product using a coal tar pitch having a softening point in the range of about 150° C. to 250° C. Also, a carbon/graphite product having a softening point in the range of about 150° C. to 250° C. A method of making mesophase pitch is formed from quinoline insoluble free coal tar pitch distillate from a high efficiency evaporative distillation process.
    Type: Grant

  • Coated pitch prill
    Patent number: 4107382
    Abstract: Process for forming coated pitch prills by mixing pitch prills with finely divided carbonaceous material and agitating the prills and carbonaceous material until a layer of carbonaceous material adherently bonded to the pitch prill is formed. Preferably the pitch prill is a substantially spherical particle having an average diameter between about 1 and about 5 millimeters. The finely divided carbonaceous material is preferably carbon black.
