Three perovskite-type compounds of composition La0.4Ca0.6Fe1-xCoxO3-d (x=o, o.25 and 0.5) were investigated for use as oxygen separation membranes for the partial oxidation (POX) of methane to syngas. Special attention was given to the question of their st ...
Data for the volumetric mass transfer coefficient, kLa, and the effective area, of structured packings have rarely been reported in the literature. This is despite the ever-increasing importance of structured packings in industrial separation columns for a ...
A CO2 laser-heated diamond anvil cell was used for performing argon solubility experiments in silicate melts. This technique allowed solubility experiments to be carried out at much higher pressures than in a piston-cylinder-type apparatus. When the beam o ...
The solubility of rare gases in silicate melts and minerals at high pressure is of importance for understanding the early history of the Earth and its present day degassing. Helium, neon, argon, krypton and xenon were originally incorporated into the Earth ...
The oxidn. of CO on silica-supported hematite (Fe2O3) was studied by the step-response method in a tubular fixed-bed reactor at temps. 270-350 Deg. The oxidn. process appeared to proceed in two stages. First, oxygen atoms adsorbed on the surface of hematit ...
A consortium was created to investigate electroceramic materials that show ionic or mixed ionic-electronic conduction (MIEC), for application as oxygen separation membranes and in solid oxide fuel cells (SOFC, electrolytes and cathodes). The focus is on de ...
The separation of hydrogen isotopes for applications such as nuclear fusion is a major challenge. Current technologies are energy intensive and inefficient. Nanoporous materials have the potential to separate hydrogen isotopes by kinetic quantum sieving, b ...
