The influence of potassium and calcium species on the swelling and reactivity of a high–swelling South African coal

Collins, Anna Catharina (2014)

Alkali compounds were added to a South African coal with a high swelling propensity and the behaviour of the blends were investigated. A vitrinite-rich bituminous coal from the Tshikondeni coal mine in the Limpopo province ...
The influence of various potassium compound additions on the plasticity of a high-swelling South African coal under pyrolyzing conditions

Strydom, C.A.; Collins, A.C.; Bunt, J.R. (Elsevier, 2015)

The influence of the anion attached to a potassium cation on the decrease of plastic properties of a high swelling vitrinite-rich medium rank B South African coal was investigated by adding potassium hydroxide (KOH), ...
