Conclusions
It may be concluded that data acquired from certain bench-scale tests may be useful to the coke plant operator if the qualitative nature of the data is recognized, and if used largely for screening purposes.
Coal petrography most closely approaches the ideal method.
Conclusions drawn from bench-scale test data require confirmation in pilot-scale test ovens before being applied to commercial practice. However, bench-scale test data, properly applied, can reduce the amount of pilot oven runs required.
