loped and applied, is upgraded brown coal (UBC) process. UBC process was developed as the pre-treatment process of BCL (brown coal liquefac-tion) based on slurry dewatering process. The condition of the upgrading process at the tempera-ture of about 140°C and the pressure of 0.35 MPa, is much milder than those of other upgrading pro-cesses.

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.
