The impact of particle size and maceral segregation on char formation in a packed bed combustion unit
Malumbazo, N.; Wagner, N.J.; Bunt, J.R. (ELSEVIER, 2013)Highveld parent coal was crushed into three size fractions, namely: 5 mm–75 mm, 5 mm–53 mm, and 5–37.5 mm. The crushed samples were subjected as feed coals to heating in a packed-bed reactor to investigate the influence ... -
The petrographic determination of reactivity differences of two South African inertinite-rich lump coals
Malumbazo, N.; Wagner, N.J.; Bunt, J.R. (Elsevier, 2012)There is limited literature on the classification and characterization of chars generated from lump coals during synthesis gas production, especially from a South African perspective. Two inertinite-rich medium rank C ... -
Structural analysis of chars generated from South African inertinite coals in a pipe-reactor combustion unit
Bunt, John Reginald; Malumbazo, N.; Wagner, N.J.; Van Niekerk, D.; Assumption, H. (Elsevier Science, 2011)An inertinite-rich medium rank C bituminous South African coal was utilized to generate chars in a pipe-reactor combustion unit. This unit generates chars at atmospheric pressures and temperature was controlled with N2 to ...
