Today there is a growing trend towards the use of higher melting binder pitches in the manufacture of prebaked anodes. Although 110-112°C Softening point Mettler pitches are still the dominant quality for prebaked anodes, the use of 120M pitches is growing and some anode producers are even using 130M pitches on a routine basis. Due to their increased coking value, higher softening point pitches provide several property benefits over standard binders and total PAH levels are lower. Binders up to 150M can be still produced with conventional distillation technology and processing of these binders should be achievable in modern paste plants with relatively minor upgrades. Today’s generation of paste mixers are already capable of processing carbon paste up to 250°C. The paper gives an overview of binder properties in the range of 112-150M and presents the results of pilot anode testing with these binders.
