Upgraded brown coal (UBC) process has been discussed elsewhere. This process has been developed to produce an upgraded low rank coal with quality similar to a bituminous coal which is acceptable commercially and has low moisture content. Three Indonesian low rank coals,
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.
Bulk samples of upgraded brown coal (UBC) will be supplied for trial use mainly to a number of power companies in Japan as well as Indonesia. Following successful demonstration, Kobe Steel will begin commercial marketing of the UBC Process from fiscal 2010, which begins in April 2010.
dec 29, 2010 development of upgrading low rank coal since the early 1990s. the process, called the upgraded brown coal (ubc) process, is based on the PT UPGRADED BROWN COAL INDONESIA (UBCI) a subsidiary from Kobe Steel Ltd., is urgently seeking for professional candidate to
The Upgraded Brown Coal (UBC) Process is a new technology to convert low rank coal into transportable solid fuel with higher heat value without trouble of spontaneous combustion. UBC demonstration plant with the capacity of 3 ton/day had constructed in

The Upgraded Brown Coal (UBC) process is a new technology to convert low rank coal into transportable solid fuel with higher calorific value without trouble of spontaneous combustion. A pilot plant with a capacity of 3 ton/day had been constructed on Java Island in Indonesia and operated to acquire data for feasibility study.

01/10/2011#0183;#32;Upgraded brown coal (UBC), a wellknown 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 130160 #176;C under pressure of to MPa [1], [2] .
Among them, UBC (upgraded brown coal) process developed by Kobe Steel Ltd., Japan will be applicable (Deguchi, et. al., 2002). The process upgrades a LRC and reduces moisture content to be equal to high rank coal. Therefore, it is expected to decrease the susceptibility to spon

Upgraded Brown Coal (hereinafter referred to as quot;UBC#174;quot; 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 minemouth power generation based on UBC powder. 1. Development of
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? ) made from Indian lignite to verify its applicability in improving the efficiency of minemouth power generation. As a result, it has been confirmed that UBCbased power generation is superior to the existing lignitebased power
Upgraded brown coal (UBC) process has been discussed elsewhere. This process has been developed to produce an upgraded low rank coal with quality similar to a bituminous coal which is acceptable commercially and has low moisture content. Three Indonesian low rank coals, Berau, Tabang and Samaranggau
Upgraded Brown Coal (UBC) process is one of the best upgrading technologies that can be implemented. Moreover, the low cost production of LRC and the availability of infrastructures would be the more attractive for UBC commercialization. Based on the coal quality specification recommended in this paper, the total moisture of the LRC varies from
One of these processes is the Upgraded Brown Coal (UBC) process developed by Kobe Steel Ltd. In this study, an Indonesian LRC was processed using the UBC bench scale unit of 100 kg/day at a
23/05/2007#0183;#32;The UBC Process raises the heat value of brown coal 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.
1999). Among them, UBC (upgraded brown coal) process developed by Kobe Steel Ltd., Japan will be applicable (Deguchi, et. al., 2002). The process upgrades a LRC and reduces moisture content to be equal to high rank coal. Therefore, it is expected to decrease the susceptibility to spontaneous combustion.
