- 4D2. Low-rank Coal Upgrading Technology (UBC Process)
adaptation of the slurry dewatering technique in the brown coal liquefaction process, consists of 3 stages: 1) slurry preparation dewatering, 2) solid-liquid separation solvent recovery, and 3) briquetting (Fig 1) Fig 1 UBC process for upgrading low-rank coal During the slurry preparation dewatering stage, after the
- Demonstration of Upgraded Brown Coal (UBC Process by 600 . . . - KOBELCO
2) Slurry dewatering This step includes mixing the crushed coal with light oil containing a heavy oil, such as asphalt, in a slurry preparation tank to prepare the coal slurry This is followed by putting the coal slurry into a slurry dewatering tank, and Detail By "JCOAL" jointed by Kobe Steel Ltd with the partnership of Arutmin Bumi Resources
- Coal Beneficiation - Alfa Laval
Our solid-liquid separation solutions are an effective, proven, high capacity solution for dewatering coal tailings and mine wastewater They are also an effective solution for recovery of fine coal from flotation concentrate as well as from lean streams
- 25. 褐炭の油中脱水によるクリーン固体燃料の製造
The UBC process consists of a coal-oil slurry dewatering, coal-oil separation and oil recovery sections This paper focuses on the behaviour of the coal during dewatering and the effects of oil and asphalt on the properties of the upgraded coal such as oxidation reactivity and spontaneous heating
- Dewatering Technology for Coal at Normal Temperature Using DME
In order to have a more stable supply of coal, sub-bituminous coal and brown coal, which are currently underutilized, must be utilized on a larger scale CRIEPI has invented a new dewatering process that uses DME (dimethyl ether)＊1 as the dewatering agent
- ハイパーコール利用コークス製造技術
Hyper-coal (HPC) is an ashless coal, which is made by applying solvent de-ashing technology Coal is extracted with coal derived recycling solvent, which consists mainly of 2-ring aromatics, at 360-400℃, and insoluble coal including ash is removed by gravity settling We can feature the Hyper-coal as an ashless, high heat value (8,500kcal kg
- Kobe Steel to begin construction of upgraded brown coal demonstration . . .
Kobe Steel began development of the UBC Process in 1993, applying slurry dewatering technology used in coal liquefaction to upgrade low-rank coal Using a 100-kg-per-day bench-scale unit built at Kakogawa Works, Kobe Steel began working on the practical application of the process in the mid-1990s
- Study on Development of Ecological and Highly Efficient Combustion . . .
developed by Kobe Steel can increase the quality of low–rank coal by means of a slurry dewatering technique at low temperature and pressure without chemical reactions The technology produces binderless briquettes in a double–roll press from low–rank coals predried in a light oil slurry
