Coal-derived low smoke fuel assessment through coal stove combustion testing

Kühn, Thys; Bunt, John R.; Neomagus, Hein W.J.P.; Piketh, Stuart J.; Everson, Raymond C.; Coetzee, Sansha (Elsevier, 2017)

A study was undertaken to investigate the production of low smoke fuel from coal currently used in low-income households in South Africa. Pyrolysis of large coal lumps was studied as a possible production method, and an ...
The effect of added minerals on the pyrolysis products derived from a vitrinite-rich demineralised South African coal

Roets, Leon; Bunt, John R.; Neomagus, Hein W.J.P.; Strydom, Christien A.; Van Niekerk, Daniel (Elsevier, 2016)

A better understanding of the behaviour of the inorganic matter present in coal will assist in more cost-effective operations and more consistency in product yield and composition during thermal processing. In this study, ...
Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition

Bean, N.C.; Bunt, J.R.; Strydom, C.A.; Neomagus, H.W.J.P.; Van Niekerk, D. (SAIMM, 2018)

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 ...
