Production of coal tar/petroleum pitch by the combined distillation of coal tar and heavy cycle oil at JSC Gubakhinskii Koks

Resumo

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, 306 t 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.
