Coal upgrading technology refers to a class of technologies developed to remove moisture and certain pollutants from low rank coals such as subBituminous coal and lignite (brown coal) and raise their calorific values. Companies loed in Australia, Germany and the United States are the principal drivers of the research, development and commercialisation of these technologies.
generally better compared with those of the upgraded coal by the UBC process. It could be understood, because the UBC process was held in lower temperature and lower pressure compared to those of the HWD and SD processes. In the future, the upgraded coal is possible in the form of the coal water mixture (CWM), which could be pumped by pipelines and
In Indonesia, the potential coal is mostly found in low and moderate calorific coal, it is classified as brown coal. Commonly, brown coal has high moisture content. Upgrading Brown Coal (UBC) process is a method for reducing the moisture content of brown coal by up to 80%.
2. UBC Process Figure 1 shows a schematic diagram of the UBC process. The UBC process developed by Kobe Steel can increase the quality of lowrank coal by means of a slurry dewatering technique at a low temperature and pressure without chemical reactions. Kobe steel started developing this UBC process for Australian brown coal in 1993.
Coldry and Matmor process – In this process, Lignite is crushed and made into pellets which are dried using hot air and then iron ore is added to make the pellets suitable as reduction agents in iron ore purifiion process. Upgradation of Brown Coal (UBC) Reducing moisture in raw lignite at site and increasing calorific value will reduce

Refined coal is the product of the appliion of a coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and/or processes that alter the characteristics of a coal before it is burned.
The UBC Process raises the heat value of brown coal 1.5 times, to the same level as highrank bituminous coal and has only onethird the ash. At the same time, it solves the problem of shipping and storage limitations, making possible the utilization of upgraded coal as a substitute for highrank coal.
Research Highlights Ash deposition of Upgraded Brown Coal(UBC) with low ash melting point is evaluated. Blending UBC with bituminous coal played a role in reducing molten slag fraction. Solid phase of aluminosilies were produced due to bituminous coal blending. Proper blending enables to be used without any ash deposition problems in boiler.
