ПОЛУЧЕНИЕ И ПРОМЫШЛЕННЫЕ ИСПЫТАНИЯ КОМПАУНДНОГО НЕФТЕКАМЕННОУГОЛЬНОГО СВЯЗУЮЩЕГО В ОАО «РУСАЛ КРАСНОЯРСК»

The developed laboratory technology of compounding coal tar and petrochemical products followed by distillation was tested under industrial conditions. The produced pilot batch of the pitch compound had a lower content of benzo(a)pyrene compared to traditional coal-tar pitch that should reduce harmful emissions in the aluminum industry. An experimental batch of the compound pitch was used in the production of under-pin anode paste. It was noted that changing current-carrying pins on the Soderberg anodes installed on the experimental under-pin anode paste was performed in the normal mode, electrolytic cell operation was normal, and no anode failures were recorded.
