2. Upgraded Brown Coal KOBE STEEL, LTD.

The Tempura Method for creating UBC is as follows: 1) Take pulverized brown coal several millimeters in size and mix it with oil containing asphalt to make a slurry. 2) Heat the slurry until the moisture in the coal evaporates. Fill the crevices of the brown coal with asphalt to prevent spontaneous combustion. 3) Separate the oil from the UBC and form the UBC into briquettes.

22 Demonstration of Upgraded Brown Coal (UBC) process

The Upgraded Brown Coal (UBC) process is a new technology to convert low rank coal into transportable solid fuel with higher calorific value without trouble of spontaneous combustion. A pilot plant with a capacity of 3 ton/day had been constructed on Java Island in Indonesia and operated to acquire data for feasibility study. Stable continuous operation of the plant had been demonstrated using ...
