Victorian brown coal in Australia has huge reserve (202 GT) and is only used for power generation near its mines. This is becase it contains more than 60 wt% moisture and ignites spontaneously after drying. Nippon Brown Coal Liquefaction Co. (NBCL) has developed the BCL (Brown Coal Liquefaction) process which converts the brown coal into high value liquid fuel for trasportation such as gasoline under high temperature and high pressure conditions. This process is a two-stage direct liquefaction process and consists of four unit sections: dewatering, primary hydrogenation, solvent de-ashing, and secondary hydrogenation. This paper reviews the direct coal liquefaction technology, and the detail of the BCL process which has been confirmed by operation of the 50 T (dry coal) /D pilot plant constructed in Australia.
