Comparing the porosity and surface areas of coal as measured by gas adsorption, mercury intrusion and SAXS techniques
(Elsevier, 2015)In this paper, we compare the surface area, porosity and other physical–structural properties of four bituminous coals from three different coal fields of South Africa determined using carbon dioxide (CO2) and nitrogen ... -
DC electrical conductivity of nano-composite polystyrene–titanium– arsenate membrane
(ELSEVIER, 2013)In continuation to our previous work with nano-composite polystyrene–titanium–arsenate (PS–Ti–As), we further extended the characterization by means of DSC, TEM and mercury porosimetry measurements. In addition to the ... -
A predictive model for the selectivity variables of an ammonium nitrate fluidised bed granulator
(North-West University (South Africa), 2019)A model for the inference measurement of the selectivity variables of an ammonium nitrate fluidised bed granulator was investigated. Fluidised bed granulators are complex due to numerous processes occurring in one vessel ... -
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 ...
