An ab initio study on the transition path of carbon dioxide at high pressure: evidence for a new intermediate P(4)over-barm2 phase
(Elsevier, 2019)The structural and dynamical behaviour of seventeen solid polymorph of the non-molecular CO2 compound was evaluated using the full potential linear augmented plane wave method (FP-LAPW) in the framework of density functional ... -
Carbon dioxide capture from flue gases using dry sorbents
(North-West University (South Africa)., 2021)The project entails capturing CO2 produced from industrial flue gases with dry adsorbents through gas adsorption to mitigate the CO2 emissions. Four commercially available activated carbon samples (CQ006, CQ30P, CQ650 and ... -
Feasibility of thorium extraction from a solid monazite matrix utilizing supercritical CO2 with TBP and HFA as chelates
(2014)With current energy demands globally and locally, nuclear energy remains one of the top competitors for cleaner and sustainable energy. The nuclear industry requires more inherent safety and proliferation resistance in ... -
Granulites, CO2 and graphite
(Elsevier, 2012)Externally derived, pure CO2 that mixes with a carbon-(under)saturated C-O-H-fluid in lower crustal granulites may result in graphite precipitation if the host-rock oxygen fugacity (fO2rock) is below the upper fO2 limit ... -
The influence of potassium carbonate and potassium chloride during heat treatment of an inertinite–rich bituminous char
(North-West University, 2012)Thermogravimetry, coupled with a mass spectrometer (TG-MS) was used to investigate the catalytic effect potassium carbonate (K2CO3) and potassium chloride (KCl), on the char conversion and the product gas composition of ... -
Theoretical and experimental analysis of supercritical carbon dioxide cooling
(2014)With on-going developments in the field of trans-critical carbon dioxide (R-744) vapour compression cycles, a need to effectively describe the heat transfer of supercritical carbon dioxide for application in larger diameter ...
