Production of Coal Tar/Petroleum Pitch by the Combined Distillationof Coal Tar and Heavy Cycle Oil at JSC Gubakhinskii Koks

摘要

Coal tar/petroleum pitch has been produced by the combined distillation of coal tar and heavy cycle oil from catalytic cracking, in industrial trials. In processing a 60 : 40 mixture of those components, 3061 of pitch that meets the requirements for anode binder is produced. The benzo[a]pyrene content is lower in the petroleum-coal pitch than in regular coal pitch used in electrode production.
