Abstract
Способ получения анизотропного нефтяного пека путем термообработки изотропного нефтяного пека в инертной атмосфере при температуре 350-450°C и атмосферном давлении в течение 20-100 ч, последующей экстракцией изотропной части полученного гетерофазного пека толуолом при температуре 330-350°C и давлении 10-20 МПа, отгоном толуола и обработкой полученного анизотропного пека в ультразвуковом поле, отличающийся тем, что образующиеся в процессе термообработки газы и дистиллятные продукты отводятся, подвергаются охлаждению и конденсации с последующим разделением на легкую и тяжелую дистиллятную фракцию с температурой кипения 350-450°C, осуществляется возврат тяжелой дистиллятной фракции на стадию термообработки нефтяного пека в количестве 40-50% масс. по отношению к изотропному пеку.The method of producing anisotropic oil pitch by heat treatment of an isotropic oil pitch in an inert atmosphere at a temperature of 350-450 ° C and atmospheric pressure for 20-100 hours, followed by extraction of the isotropic part of the resulting heterophase pitch with toluene at a temperature of 330-350 ° C and a pressure of 10-20 MPa, distillation of toluene and processing of the obtained anisotropic pitch in an ultrasonic field, characterized in that the gases and distillate products formed during the heat treatment are discharged, subjected to cooling and condensation, followed by separation into a light and heavy distillate fraction with a boiling point of 350-450 ° C, the heavy distillate fraction is returned to the stage of heat treatment of oil pitch in an amount of 40-50% of the mass. in relation to isotropic pitch.
