Abstrakt: The use of coal pitch as a binder in anode production for the aluminum industry is an outdated approach. Such pitch has a high content of carcinogens, polycyclic aromatic hydrocarbons, and tar phenols, and its environmental impact is unacceptable. A possible alternative binder, which is free of these problems, is environmentally benign petroleum pitch from heavy petroleum residues. Current petroleum pitch must meet requirements on factors such as its physicochemical parameters, production characteristics, and the conditions of transportation and storage. Environmental constraints are especially important on account of current global conditions. These requirements are met by a new product: petroleum pitch for the production of anode mass. This pitch has similar properties to coal pitch of grades A and B1. In the present study, it is investigated by up-to-date physicochemical methods. [ABSTRACT FROM AUTHOR]
