Study on the cleaning of Peifeng coal with oil agglomeration

摘要：

　　Samples from Peifeng were studied to further investigate the influence of particle specific surface area,oil dosage,system energy input and the concentration of electrolyte on the cleaning of Fujian coal with oil agglomeration.The results showed that specific surface area of coal particles around 24m2·g-1 led to the minimum value of ash content 3.14% obtained,and sulfur content decrease from 2.0% to 0.44%; After 10 min of stirring at 2400r·min-1,the minimum product ash content 3.8% was obtained.Within the dosage range studied,considerable ash content reduction occurred with NaCl in appropriate concentrations used,in contrary,the other five other electrolytes would,to varying degrees,put a raise on ash content.No positive correlation was shown between product ash content and solid concentration,in fact,the former fell with the increasing of the latter within a certain range.
