A 8.4 t/d pilot plant was completed in November 1994. Experimental operation for continuous tests have been carried out since December 1994. Two kinds of Indonesian sub-bituminous coals and an Australian lignite were upgraded and slurrified by the end of 1995. Typical pilot test results, such as coal concentration of upgraded sub-bituminous CWM of 65% and 4,700 kcal/kg heating value, were better than the authors expected. And subsequent combustion test in a 200 kg/h furnace was also successfully completed, with results showing very good combustibilities. This R and D is now in its final year, and the authors are conducting combustion tests on a big burner and gasification test, which will be carried out until March 1996. The test results from the pilot plant so far confirm the validity and economic feasibility of the upgrading and CWM production technology to promote the use of low rank coals (LRCs). The authors are convinced that this technology has great potential for the production of low cost CWM.
