In this process under development, coal was mixed with sodium hydroxide solution (0.6 NaOH/g coal), thermally dried and then subjected to microwave radiation. Finally, the coal was leached with dilute HCl. A rough summary of the results shows that approx. 1/3 of the sulfur and usually more than half the original ash was removed from Illinois No. 6 float coal (28 x 0). The process has been described more fully in (GE-COAL-007, Dec. 8, 1982). Process design and cost estimates are being developed. (LTN)
