“…The unit cell lattice parameters of the a-Ti phase were larger than that of pure aÀTi, which indicates that the HCP phase contained hydrogen and/or oxygen. This result is in agreement with in situ SR-XRD data obtained in our previous work [16], in which we reported that high amounts of the HCP a-phase were not converted to hydride during rehydrogenation in a gas mixture containing CO. Furthermore, the original sample was only partially recovered after the exposure to CO.…”

“…Non-isothermal cycling of hydrogen absorption-desorption in a gas flow mixture of H 2 þ CO has been reported by the present authors earlier [16]. The experiments showed that reversible hydrogenation took place at the end of the 4th cycle and led to formation of g-(TiV)H 1.45 with a body centered tetragonal unit cell (distorted face centered cubic lattice).…”

“…The study [16] showed that hydrogenation-dehydrogenation occurred even when the gas mixture contained a substantial amount of CO. However, significant degradation was observed leading to a decreased reversible hydrogen capacity during the cycling.…”

“…In a previous publication [16], hydrogen sorption properties and in situ synchrotron X-ray diffraction study of TieV alloys interacting with hydrogen gas mixed with CO were reported. The study [16] showed that hydrogenation-dehydrogenation occurred even when the gas mixture contained a substantial amount of CO.…”

“…The H absorption process often requires higher temperatures and, correspondingly, usage of hydride-forming materials characterised by higher hydride stabilities: LaNi 4 Cu [5], Ti-based alloys and composites [7,16], activated Mg [12], or Pd alloy [15]. At the same time, a challenging problem that hampers application of MH for hydrogen separation from the mixtures containing chemically-aggressive gases (O 2 , H 2 O, CO, sulphur-containing compounds, etc.)…”

Modibane, K.D. et al. (2013). Poisoning-tolerant metal hydride materials and their application for hydrogen separation from CO2/CO containing gas mixtures. AbstractMetal 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 performances resulting from the surface chemical action of electrophilic gases. In this work, the feasibility study of poisoning tolerance of surface modified AB5-type hydride forming materials and their application for hydrogen separation from process gases containing carbon dioxide and monoxide was carried out. Target composition of La(Ni,Co,Mn,Al)5 substrate was chosen to provide maximum reversible hydrogen capacity at the process conditions. The selected substrate alloy has been shown to be effectively surface-modified by fluorination followed by electroless deposition of palladium. The surface-modified material exhibited good coating quality, high cycle stability and minimal deterioration of kinetics of selective hydrogen absorption at room temperature, from gas mixtures containing 10% CO2 and up to 100 ppm CO. The experimental prototype of a hydrogen separation unit, based on the surfacemodified metal hydride material, was tested and exhibited stable hydrogen separation and purification performances when exposed to feedstocks containing concentrations of CO21. Introduction Metal hydride (MH) materials have found a number of promising gas-phase applications in processes of considerable economic potential, such as hydrogen storage, separation and recovery, thermally-driven compressors and heat pumps, etc. [1e3]. These materials exhibit a favourable combination of their properties, including reversibility and selectivity of interaction with H 2 gas at mild conditions, high volumetric density of hydrogen in the solid, significant heat effects in the course of hydrogenation/dehydrogenation. Thus they are very flexible in the applications, and often allow to develop multifunctional facilities (e.g., for hydrogen storage, purification and controlled supply) which offer to an end-user safe, efficient and cost-saving solutions [4].
