  • Coal tar and hydrocarbon mixture pitch and the preparation and use thereof
    Publication number: 20060230982
    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.

  • Coal tar and hydrocarbon mixture pitch production using a high efficiency evaporative distillation process
    Publication number: 20050263436
    Abstract: Described are methods that utilize high efficiency evaporative distillation to make a high softening point coal tar pitch, a quinoline insoluble-free and ash-free coal tar pitch having a desired softening point, and a mesophase coal tar pitch. Each of the methods uses a feed coal tar pitch having a softening point in the range of 70° C. to 160° C. The methods may be carried out using appropriate conventional distillation equipment, a wiped film evaporator, or a thin film evaporator.
