Abstract
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.
