This report describes activities for the sixth quarter of work performed under this agreement. MEFOS conducted a third round of atmospheric testing as scheduled on December 9 through December 12, 2003. We reported experimental activities of this testing last quarter. We report process calculations and results this quarter. The test results demonstrated a much-improved rate of carbon dissolution with gas yields close to thermodynamic equilibrium at nearly doubled feed rates of September testing and a commercially viable feed and oxygen injection technique. Additional super-atmospheric testing to perform the last task in the MEFOS experimental program is scheduled for the last quarter of 2004.
