Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition
South African coal is mainly used for electricity generation by means of pulverized fuel combustion and liquid fuels production via indirect gasification technology and Fischer-Tropsch synthesis. In order to expand the ...
Drying of coal fines assisted by ceramic sorbents
It is proposed to introduce contact sorption drying as a method to reduce the moisture content in coal fines. The aim of this study was to investigate the possibility of drying fine and ultra-fine coal using porous ceramic ...
Coal product moisture control using stockpiles
The moisture content of product coal is a major factor influencing the efficiency of downstream coal utilization processes. Product stockpiles are often used as a control measure to regulate the moisture content of the ...
Simulation of washability and liberation information from photographs
Imagine that a sample of coal could be crushed unlimited times to the same or different top size; a different washability would be obtained for each crushing experiment. Depending on the size and distribution of the raw ...
Preparation of biochars for co-gasification from sweet sorghum bagasse
(ETA-Florence Renewable Energies, 2015)
Biochar is a solid product obtained through torrefaction, liquefaction or pyrolysis of organic material. It can be used for soil amendment, activated carbon for sequestration, or as bio-coal for gasification or co-gasification. ...
