Gas mixtures such as H.sub.2 /CO.sub.2 may be separated by passage through a filter bed of nanocrystalline ceramic particles on a bed of alumina particles.

Method of forming separation membranes

Mixture of gases such as hydrogen/carbon dioxide may be separated by use of membrane formed by reaction of an aluminum alkoxide with steam at high temperatures and pressures.

Separation by membrane techniques

A porous support layer is loaded with blocking liquid, such as an alcohol, prior to contact with an aluminum alkoxide to form thereon a layer of alumina which is dried and calcined to yield a membrane suitable for separation of gases.

Method of forming membranes useful for separation of gases

Mixture of gases such as hydrogen/carbon dioxide may be separated by use of membrane formed by reaction of an aluminium alkoxide with water vapor at high temperatures and pressures.

Membrane separation of gases

This invention provides a variable length membrane module for separation of fluids in solution. The module comprises a series of hollow fiber membranes, a tubing surrounding the series of hollow membranes, an outer steel tube encasing the series of hollow membranes and a pair of nuts arranged to engage the tubing to adjust the length of the hollow fiber membranes to allow proper passage of the fluids therethrough.
