Application of surface-modified metal hydrides for hydrogen separation from gas mixtures containing carbon dioxide and monoxide
Lototskyy, Mykhaylo; Modibane, K.D.; Williams, M.; Klochko, Ye.; Linkov, Vladimir; Pollet, Bruno G. (Elsevier, 2013)Application of surface-modified MH material for H2 separation using temperature/pressure swing absorption–desorption was studied. The substrate alloy had the following composition LaNi3.55Co0.75Al0.4-Mn0.3, and the surface ... -

Williams, M.; Sibanyoni, J.M.; Lototskyy, Mykhaylo; Pollet, Bruno G. (Elsevier, 2013)Hydrogenation behaviour, structure, morphology and dehydrogenation/re-hydrogenation performances of Mg–Pd nanocomposites prepared by high-energy reactive ball milling in H2 (HRBM) of Mg in the presence of amorphous and ... -
Magnesium–carbon hydrogen storage hybrid materials produced by reactive ball milling in hydrogen
Lototskyy, Mykhaylo; Sibanyoni, J.M.; Denys, R.V.; Williams, M.; Pollet, Bruno G.; Yartys, V.A. (Elsevier, 2013)Time-resolved studies uncovered kinetics and mechanism of Mg–hydrogen interactions during High energy reactive ball milling in hydrogen (HRBM) in presence of various types of carbon, including graphite (G), activated carbon ... -
Poisoning-tolerant metal hydride materials and their application for hydrogen separation from CO2/CO containing gas mixtures
Modibane, K.D.; Williams, M.; Lototskyy, Mykhaylo; Davids, M.W.; Klochko, Ye.; Pollet, Bruno G. (Elsevier, 2013)Metal hydride materials offer attractive solutions in addressing problems associated with hydrogen separation and purification from waste flue gases. However, a challenging problem is the deterioration of hydrogen charging ...
