Additive Selection for Coal Tar Pitch Modification in Aluminum Industry

This paper describes the method undertaken to establish an additive selection method which would yield improved coke wettability by modified pitch and presents the results for three different additives. Non-modified and modified pitches were characterized by carrying out wettability tests and FTIR analyses. Coking values of non-modified and modified pitches were also measured. The results show that it is possible to improve coke-pitch interactions via the utilization of additives.
