CHEMICAL AND PHYSICAL PROPERTIES OF UPGRADED BROWN …
Among them, UBC (upgraded brown coal) process developed by Kobe Steel Ltd., Japan will be applicable (Deguchi, et. al., 2002). The pro-cess upgrades a LRC and reduces moisture con-tent to be equal to high rank coal. Therefore, it is expected to decrease the susceptibility to spon-taneous combustion. Process condition 0.35 MPa, was milder com-pared to that of other upgrading methods. …
Upgraded Brown Coal Demonstration Plant starts …
"The Upgraded Brown Coal Process can effectively utilize brown coal, an unused natural resource in Indonesia," said Yasuo Inubushi, President & CEO of Kobe Steel. "At the same time, it will be an effective way to moderate the world supply and demand of raw materials and energy." The UBC ® demonstration plant project is being undertaken by the Japan Coal Energy Center (JCOAL), in which Kobe ...
IMPROVEMENT OF LOW RANK COAL …
Various coal upgrading processes were conducted i.e. upgraded brown coal (UBC), hot water drying (HWD) and steam drying (SD). The UBC process was carried out in pilot scale with a capacity of 5 tons/day at temperature of 160°C and pressure of 0.35 MPa, while the HWD and SD pro- cesses were conducted in laboratory scale using autoclave at the temperature of 300ºC and pressure of about 12 …

Refined coal - Wikipedia
Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.

2. Upgraded Brown Coal || KOBE STEEL, LTD.
Prone to spontaneous combustion, brown coal is hardly ever used. On the other hand, because brown coal is noted for its low ash and sulfur, it has the advantage of being environment-friendly when burned. By removing the moisture, Kobe Steels UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource.
