CO2 reactivity of briquettes derived from discard inertinite-rich Highveld coal using lignosulphonate and resin as binders
Leokaoke, N.T.; Bunt, J.R.; Neomagus, H.W.J.P.; Waanders, F.B.; Strydom, C.A. (SAIMM, 2019)South African collieries generate approximately 31 Mt of fine and ultrafine coal annually, with the majority of the ultrafine fraction discarded in slurry ponds and underground workings. Use can be made of this energy ... -
Green coal development for application in fixed-bed catalytic gasification
Bunt, J.R.; Marx, S.; Waanders, F.B.; Leokaoke, N.T. (SAIMM, 2018)A novel ‘green coal’ product formulation has recently been developed and the utilization concept tested at the North-West University coal research laboratories. Hydrothermal liquefaction was used to produce bio-oil ... -
Manufacturing and testing of briquettes from inertinite-rich low-grade coal fines using various binders
Leokaoke, N.T.; Bunt, J.R.; Neomagus, H.W.J.P.; Waanders, F.B.; Strydom, C.A.; Mthombo, T.S. (SAIMM, 2018)Inertinite-rich, low-grade coal was used with 12 binders: clays (attapulgite and bentonite), biochar, cow dung, crystallized medium-tar pitch, coal tar sludge, flocculant, fly ash, lignosulphonates, polyester resin, and ... -
Testing of briquettes made from Witbank coal fines with polyvinyl alcohol as binder
Henning, C.N.; Leokaoke, N.T.; Bunt, J.R.; Waanders, F.B. (EARET, 2018)Approximately 12% of South Africa’s mined coal can be classified as fine coal. Fine coal is primarily formed through mechanical mining methods and can cause blockage in equipment, transportation mechanisms and silos. ...
