Evaluation of the mod 1 continuous bench-scale reactor was completed. A 3% mass balance error was obtained in the final test series using Pittsburgh and Upper Freeport coals, well within the target 10% maximum. Based on operating experience, a mod 2 design was finalized and installation is nearly complete. This design is expected to overcome problems caused by foaming. Pittsburgh coal, which was found to foam and requires aggressive reaction conditions to clean, was selected for testing in the mod 2 reactor. Laboratory batch data were used to study the variation found within four different Pittsburgh seam coal samples and the effect of particle size. Reactor stirring effects also were studied in support of the mod 2 design.
