Separation of oxygen from air is performed in a continuous, cyclic manner using vanadium bronze liquid slurries as reversible chemical absorbents, absorbing at elevated temperature and desorbing at lowered temperature.

High temperature oxygen recovery with reversible chemical reaction

The present invention is directed to catalysts for the absorptive separation of oxygen from oxygen-containing gas mixtures, such as air, using reversible chemical reaction systems, such as, ##STR1## The catalytic action is the result of the addition of transition metal oxides to the oxygen accepting system.

Catalysts for absorptive air separation

The present invention is a process for separating one or more components of a gas mixture. The process comprises passing the gas mixture over a membrane, which is selectively permeable to the component being separated, due to one or more reversible reactions between the component desired to be separated and a layer of active molten material immobilized in a suitable support material and/or encapsulated in a non-porous gas permeable polymer material.

Method for gas separation

A process for separating a gas from a mixture of gases comprises passing the gas mixture over a membrane, selectively permeable by the gas being separated, owing to the occurrence of one or more reversible oxidation-reduction reactions between a continuous layer of active molten material, immobilized in a rigid, porous, inert support therefor, and the gas being separated.
