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 low-rank 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.
This study focuses on the relationship between ash deposition characteristics and ash melting characteristics. Upgraded brown coal (UBC) and two types of bituminous coal with different melting temperatures and ash compositions were used as samples. The deposition tests were conducted using a refractory furnace.
The UBC Process raises the heat value of brown coal 1.5 times, to the same level as high-rank bituminous coal and has only one-third 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 high-rank coal.
The low temperature oxidation and spontaneous combustion characteristics of dried coal produced from low rank coal using the upgraded brown coal (UBC) process were investigated. To this end, proximate properties, crossing-point temperature (CPT), and isothermal oxidation characteristics of the coal were analyzed.
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 alumino-silicates were produced due to bituminous coal blending. Proper blending enables to be used without any ash deposition problems in boiler.

Based on that, CWM-making experiments performed through firstly coal-upgrading process. In this case, the coal results from the pilot plant process Palimanan UBC, West Java, Indonesia and are called Upgraded Brown Coal Water Mixture. The characteristics of coal as raw material for UBCWM can be seen in Table 1 and UBCWM's manufacturing process ...
Demonstration of Upgraded Brown Coal (UBC Process by … early 1990s. The process, called the upgraded brown coal (UBC) process, is based on the principle of "tempura (Japanese battered deep-fried food)" and ... commercial plant 2) to evaluate the applicability of UBC by conducting ...
Coal upgrading technology refers to a class of technologies developed to remove moisture and certain pollutants from low rank coals such as sub-Bituminous coal and lignite (brown coal) and raise their calorific values. Companies located in Australia, Germany and the United States are the principal drivers of the research, development and commercialisation of these technologies.
Highlights Effect of MgO addition to upgraded brown coal on the ash deposition is evaluated. MgO addition played a role in decreasing in molten slag fraction. Mg formed solid composites with Si, Fe, Al, Ca, and Mn. MgO addition contributed to the decreasing rate of ash deposition for the UBC.

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
strengthening cooperation on coal by introducing more efforts on clean coal technology due to the increasing dependence on coal in ASEAN. Under this MOU, both parties has agreed to target at making a handbook that will support policy makers as well as utility officers and
but also to environmental conservation. A low-rank coal upgrading technology (UBC process) has been developed to enable the effective use of such low-rank coal. This process, an adaptation of the slurry dewatering technique in the brown coal liquefaction process, consists of 3 stages: 1) slurry
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.
1999). 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 ...
The preparation of upgraded brown coal water mixture (UBCWM) by using an Indonesian upgraded coal that was produced by an upgraded brown coal (UBC) process in pilot scale, was carried out to obtain the effect of dispersing and stabilizing additives on rheological behaviour of the UBCWM.
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 purification process. Upgradation of Brown Coal (UBC) - Reducing moisture in raw lignite at site and increasing calorific value will reduce ...
UBC (Upgraded Brown Coal) Process at a Glance • Developed by Kobe Steel, Japan and originally subsidized by METI. • Removes moisture completely from lignite by highly energy efficient coal-oil slurry dewatering technology. (Lignite of TM 52% & 2,830 kcal/kg → UBC of TM 0% & 5,900 kcal/kg)
The high moisture content in brown coal causes its power-generating efficiency to be considerably lower than that achieved by bituminous coal. 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?

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.
