The characterisation of slow-heated inertinite- and vitrinite-rich coals from the South African coalfields

Roberts, Mokone J.; Everson, Raymond C.; Neomagus, Hein W.J.P.; Okolo, Gregory N.; Van Niekerk, Daniel (Elsevier, 2015)

The development of coal char structures with pyrolysis has been extensively investigated but has traditionally been focused on the carboniferous coals in the northern Hemisphere. In this investigation, the properties of ...
Detailed characterization of SA high mineral matter inertinite–rich coals and density fractions and effect on reaction rates with carbon dioxide: macerals, microlithotypes, carbominerites and minerals

Everson, Raymond C.; Koekemoer, Andrei; Bunt, John R.; Neomagus, Hein W.J.P.; Schwarz, Christopher (SAIChE, 2013)

An investigation was undertaken to determine the distribution of macerals and minerals in South African Highveld coal deposits as well as density fractions derived from a typical deposit. The corresponding effects on ...
