Jun 03, 2008· PT UBC said its technology would also cut the ash content of the upgraded coal by a third, which would make the burning of the fuel more environmentally friendly, while the briqeutted coal .
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 ...

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.

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.

Upgraded Brown Coal (hereinafter referred to as "UBC®" note)). This process features a dewatering method for efficiently removing the large amount of moisture contained in lignite, thus increasing its calorific value. The UBC process has many applications; this paper focuses on mine-mouth power generation based on UBC powder. 1. Development of ...
Dec 29, 2015· UBC (upgrading brown coal) is a method of improving the quality of coal by using oil as an additive. Through processing in the oil media, not just the calories that increase, but there is also water repellent properties and a decrease in the tendency of spontaneous combustion of coal products produced. The results showed a decrease in the water levels of natural coal bayah reached 69% ...
Coal preparation plant Wikipedia. A coal preparation plant (CPP also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges ...
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.
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.
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 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.
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.

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.
