The rate of carbonization has important impacts on the energy consumption and the productivity in baking process of reduction anodes. In the present work the carbonization of coal tar pitch-petroleum coke mixtures with catalysts, such as S, AlCl{sub 3}, AlF{sub 3}, and Fe{sub 2}Cp{sub 2}(CO){sub 4}, was investigated by thermogravimetry (TG) and kinetic analysis of the data. It was found that the pyrolysis temperature for non-coking volatiles decreased with catalysts, and that the coke yield of pitch binder increased. Almost all the sulfur and most of the iron from the additives can be removed during heat treatment, while the remaining aluminum in the residues may not be harmful.
