The influence of pitch quality on anode carbon gasification

The objective of this research is to investigate the gasification, in air and carbon dioxide, of anode carbons used in the aluminium industry, to identify any differences in the behaviour of filler coke and the coke from the coal-tar binder pitch, and to study the effect of pitch quality, especially the type and proportion of quinoline insolubles (QI) and the sodium content, on those processes which contribute to excess anode consumption.
