Experiments were instituted in support of a continuous bench-scale unit for coal leaching. These experiments (conducted at 350/sup 0/C) were two runs in a 3-in. dia reactor, using NaOH/KOH melt and Kentucky No. 11 coal, and three runs in the TRW large Gravimelt reactor. Results show that semi-continuous addition of coal and removal of coal samples gives product coal showing the expected trend of increased removal with time and smaller particle size. The design basis and flow diagram of the bench-scale continuous leacher are given.
