Abstract:
Provided herein are the metalloborane compounds, MOF-metalloborane compositions, and hydrogen storage system used for high density hydrogen storage. The compounds and compositions may have the structure M2B6H6 or MOF-M2B6H6-dicarboxylic acid. Particularly the transition metal M may be titanium or scandium and the MOF may be MOF5. The hydrogen storage systems hydrogen absorbed to the metalloborane compounds or to the MOF-metalloborane compositions. Methods of storing hydrogen are provided comprising flowing or passing hydrogen gas for absorptive contact with the metalloborane compounds or to the MOF-metalloborane compositions. A method for calculating the hydrogen storage capacity of a metalloborane is provided in which random sampling of the thermodynamic states of a two-system model of hydrogen in the presence of a metal organic framework-metalloborane crystal structure is used to calculate probability of hydrogen absorption.
Abstract:
L'invention concerne un procédé de piégeage de l'arsenic contenu dans une solution, comprenant une étape de mise en contact de ladite solution avec une poudre comprenant des particules d'hydrate de silicate de calcium ayant un rapport molaire Ca/Si supérieur ou égal à 0,8. L'invention porte également sur un dispositif perméable permettant de mettre en œuvre le procédé selon l'invention et comprenant des nanoparticules d''hydrate de silicate de calcium ayant un rapport molaire Ca/Si supérieur ou égal à 0,8.
Abstract:
A process for manufacturing low soluble iron, medium flow rate diatomite filter aids and such filter aids are disclosed. Sodium aluminate is used as an additive. As compared to either straight calcined or soda ash flux-calcined diatomite filter aids of similar permeabilities made from the same ore, the disclosed filter aids have much lower iron solubilities. For instance, disclosed filter aids of about 0.3 to about 2.0 Darcy were made using an alkali aluminate as an additive/flux agent to have an EBC soluble iron content of less than 100 ppm versus more than 140 ppm for similar filter aids that were made from the same ore and flux-calcined with soda ash.
