Abstract
1. Способ получения мезофазного углеродного порошка путем обработки углеводородного сырья ароматическим растворителем, отделения нерастворимых частиц от продуктов обработки, осаждение из последних мезофазной пековой фракции и выделения из нее растворителя, отличающийся тем, что циркуляцию ароматического растворителя проводят в противоточном режиме в три этапа экстрагирования, корректировка, промывка с последующим гидроциклонным извлечением летучих углеводородов. ! 2. Способ по п.1, отличающийся тем, что в качестве сырья используют карбонизат каменноугольного пека. ! 3. Способ по п.1, отличающийся тем, что соотношение твердое вещество - растворитель составляет (1:20)-(1:5) мас.%. ! 4. Способ по пп.1-3, отличающийся тем, что экстракционное разделение производят при температуре кипения растворителя, давлении 0,5-2 атм, времени 5-60 мин. 1. A method of producing a mesophase carbon powder by treating a hydrocarbon feed with an aromatic solvent, separating insoluble particles from the processed products, precipitating the latter from the mesophase pitch fraction and isolating the solvent from it, characterized in that the aromatic solvent is circulated in countercurrent mode in three stages of extraction, adjustment washing followed by hydrocyclone recovery of volatile hydrocarbons. ! 2. The method according to claim 1, characterized in that the raw material is carbonizate of coal tar pitch. ! 3. The method according to claim 1, characterized in that the ratio of solid substance to solvent is (1:20) - (1: 5) wt.%. ! 4. The method according to claims 1 to 3, characterized in that the extraction separation is carried out at a boiling point of the solvent, a pressure of 0.5-2 atm, a time of 5-60 minutes
