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.

With the advanced technologies, such as Upgraded Brown Coal (UBC) process, LRC can be used optimally, particularly for the power plant. Suralaya Generation Business Unit (SGBU), which is the largest coal power plant in Indonesia, recently has to use lignite coal or low rank coal because the price of medium and high rank coal is too expensive.
Indonesia (Borneo) is an essential producer of coal in the world. Unfortunately, the resulting coal type is mostly in the low-rank, which called brown coal. This study was aimed to evaluate the influence of mixed oil coating to upgrade Borneo brown coal in terms of caloric value and water re-absorption. The additive material used to enhance brown coal is blended oil, such as used cooking oil

T1 Mine mouth power generation system based on upgraded brown coal (UBC.) AU Kashiwagi, Takeo. AU Ishino, Hiromichi. AU Takagi, Takashi. AU Hirose, Ken. PY 2014. Y1 2014. N2 Lignite (brown coal) is being used only for mine-mouth power generation.
Upgraded brown coal (UBC), a well-known coal drying process, enables the utilization of low rank coals. The UBC process removes moisture in the coal using the slurry dewatering process, which involves the evaporation of moisture in the slurry of coal and light oil containing a small portion of heavy oil (such as asphalt) at temperatures of 130
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.
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.
Isotherms of water adsorption and desorption of upgraded brown coal (UBC) were compared to those of its feedstock coals, dried and not dried. The shape of isotherms showed that UBC
Upgraded brown coal water mixture (UBCWM) preparation by using an Indonesian upgraded coal produced by upgraded brown coal (UBC) process, was carried out to study the effect of dispersing and
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.
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.
Nov 01, 2006· Abstract. Upgraded brown coal (UBC) process has been developed to produce a dry upgraded coal which is comparable with a bituminous coal. Differential thermal and thermogravimetry analyses (DTA–TG) have been applied to study the combustion characteristics of some Indonesian raw and upgraded coals produced by the UBC process.
