The low-temperature carbonization process of coal is a technology to produce high grade reformed coal corresponding to bituminous coal and coal oil corresponding to heavy oil from subbituminous coal and supply them at prices close to the present market ones. From viewpoints of diversified sources and multiple export harbors, an initial-stage survey was conducted of the whole flow from new development of undeveloped mining areas in the northwest of Sumatra, Indonesia to bringing by ships to Japan of products reformed by LFC process of the US SGI's low-temperature carbonization technology. Clean coal prepared after mining is produceable at a little higher than $12. At processing ability of 10,000 tons/day of raw coal, production is expected of approximately 5,700 tons/day of solid products of more than 6,500 kcal/kg and approximately 1,000 tons/day of low sulfur C heavy oil class oil. The finished cost of solid products is about $25/ton, which becomes about $40/ton at the harbor price in Japan. In conclusion, the project to enhance the quality of subbituminous coal by the low-temperature carbonization is promising as a total system. 10 refs., 54 figs., 30 tabs.
