Gravimelt process development. Quarterly technical progress report

OSTI ID:6476410

During the current reporting period, the Mod 2, bench-scale Gravimelt reactor was installed, shaken down and operated using a sample of 40% ash run of mine Pittsburgh No. 8 seam coal which had been mine cleaned to a level of 10.3% ash. Operation was successful and an excellent overall mass balance was achieved. Preliminary ash analyses from the test site show the above 97% ash removal calculated from run of mine was obtained as expected from previous laboratory scale tests. Large processed coal samples, prepared during the week of round-the-clock operation, were obtained for the planned washing studies and other protect requirements. 3 tables.
