Upgraded Brown Coal Ubc Process

However, there exists coal with low nitrogen, low sulfur and low ash content in low rank coal, and the utilization of such low rank coal is attractive from the view point of environmental concerns. Kobe Steel has developed a coal upgrading process, the UBC Upgraded Brown Coal process, for low rank coal.
