The impact of particle size and maceral segregation on char formation in a packed bed combustion unit
(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 ... -
Reactivity study of fine discard coal agglomerates
(Elsevier, 2015)In this laboratory study thermo-gravimetric analyses were conducted to determine the influence of the addition of an alkaline metal catalyst (K2CO3 incorporated into a fine discard coal agglomerate mixture by physical ... -
An understanding of the porosity of residual coal/char/ash samples from an air-blown packed bed reactor operating on inertinite-rich lump coal
(Elsevier, 2012)The thermal treatment of coal causes a development of internal porosity of the resultant char due to the changes in the coal char pores, i.e. the opening of original closed pores, the formation of new pores, and an increase ...
