A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700° F and typical pressures between 200 and 3,000 psi, according to known liquefaction processesAbstract The main objective of this research is to develop a thermal process for drying fine coal that (1) reduces explosion potential, (2) uses a fluidized bed with minimum elutriation, (3) produces a stable dry coal by preventing moisture reabsorption and autogeneous heating, (4) reduces fugitive dust emissions, and (5) is technically and economically feasibleDevelopment of an advanced process for drying fine coal
1 Introduction Humic acid (HA) is a kind of natural organic matters widely present in lignite, danty and natural waters (such as lakes, groundwater and rivers) (Wang et al, 2012; Kavurmaci and Bekbolet, 2013)The interaction between HA and natural mineral particles in presence of water is a very important research subject in a wide range of geochemical and environmental fields (Lei et alThe coal fines with peat are mix and the resulting well mixed mass is then pelletizing by the application of pressure in conventional equipment – stiff extrusion The coal fines and peat was conditioned at various moisture contents to observe the effects on the finished product The material then agglomerated into a granular productGranulating of coal fines using peat | SpringerLink
The method of coalbriquette preparation has been described in detail elsewhere 1, 2 Briefly, the coal was impregnated with a constant binder volume (a humic acid containing inherently potassium), mixed for 30 min, dried at 110°C, pressed (1–2 kg/cm 2) and pyrolyzed in N 2 for 2 h at different temperatures: 400, 500 and 700°C PotassiumThe use of powder materials in smelting process has some impact on the breathability of the burden, and it ultimately results in poor production and quality of industrial silicon If pelletizing is prepared by these powder materials, it not only reduces production cost but also reuses waste effectively It could protect forest resources productively and contributes to sustainable developmentThe Research on Effects of Different Binders on

An organic binder, Funa, has been developed and used in the production of iron ore pellets for direct reduction in China This paper mainly describes the effects of the binder on balling behaviorsLowgrade iron ores are finely ground and processed to recover ironbearing minerals However, the ironrich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into aReview of organic binders for iron ore concentrate

Because the binder is used at a low percentage level of the total coalbinder mixture, the contribution of the metals to the coal is very small For example, if the coal binder is 4% of the mixture, then the contribution of iron to the coal is 18 mg/kg×04=07 mg/kg Example 9 Short Proximate Analysis and FTIR Comparison of Raw and Treated CoalNew Processes for Upgrading Coal Tar to Chemicals and Technical 941 Carbon G Collin Study on the LiquidSolid Phase Equilibrium of Anthracene in Some 945 Organic Solvents Y X Song, Z Q Hu and J S Gao Study on the Composition and Structure of Coating UreaHumic Acid 949 and Its Complex L P Wu and S X ChengPROSPECTS FOR COAL SCIENCE
