Demonstration of Upgraded Brown Coal (UBC Process by 600 ...

The process, called the upgraded brown coal (UBC) process, is based on the principle of "tempura (Japanese battered deep-fried food)" and efficiently removes the water contained in low rank coal in heated light oil.1) This technical development involves a pilot plant operation in Indonesia (production base capacity, 3 tonnes/day), whose operation has lasted for four years since FY 20011), 2 ...

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 Steel's UBC Process raises the heat value, thereby converting brown coal into a high-grade energy resource.

Mine mouth power generation system based on upgraded

Kobe Steel has developed a process for upgrading brown coal by applying a unique slurry dewatering technology. A study has been conducted using the upgraded brown coal (UBC? ) made from Indian lignite to verify its applicability in improving the efficiency of mine-mouth power generation. As a result, it has been confirmed that UBC-based power generation is superior to the existing lignite ...
