Abstract: A busbar arrangement for an electrolytic cell utilized for the production of aluminum by electrolysis of molten cryolite salt where the cells are arranged in a side-by-side relationship. In the busbar, the upstream cathode collector and the downstream cathode collector of the upstream cell, the electric connecting arrangements, and the anode risers associated with the downstream cell are combined in the individual busbar modules. In each module, at least one anode riser is situated at the upstream side of the downstream cell and at least one anode riser is situated at the downstream side of the downstream cell. The anode risers at the upstream side are connected to the cathode rods of the upstream and downstream sides of the upstream cell. The anode risers at the downstream side of the downstream cell are connected to the cathode rods and cathode collectors of the downstream side of the upstream cell.

Abstract: A method of producing binding pitch for an electrode material comprises the steps of enriching and exposing. The liquefied coal pitch-based component is initially enriched with air, and then is exposed to a field of hydropercussion and cavitation pulses. In this manner, a process of oxidation of the coal pitch-based component is accelerated.
