摘要：

A petroleum pitch, developed for aluminum anodes was produced, at commercial scale, as a real alternative to coal tar pitch. Using a highly aromatic refinery stream and well designed process conditions, it is possible to produce the right chemical composition needed for a high quality binder material for anodes. Through a Dynamic Process Optimization study, the paste formulation and parameters were adjusted to produce full size anodes with 100 % petroleum pitch. The performance of baked anodes were similar to coal tar pitch anodes, with the advantage of a much lower content of carcinogenic Polycyclic Aromatic Hydrocarbons (PAH). Comparative green and baked anode properties, PAH emissions and storage stability test for molten pitch are presented.
