Novel inorganic membranes for gas separation
… amorphous silica, and supported ionic liquid membranes. Supported ionic liquid CO₂/CH₄ selective membranes were synthesized in our laboratory by applying room temperature ionic liquids (RTILs) to porous inorganic α-alumina supports. The supported ionic liquid membranes (SILMs) displayed CO₂ …

Composite inorganic membranes for hydrogen reaction, separation and purification.
Silica-alumina composite membranes for hydrogen separation and high temperature chemical reactions were prepared using both conventional and modified dip-coating techniques. These were deposited on commercially available a.-alumina macroporous support of 10 millimetre (mm) outer diameter, 7 mm …

Development and testing of inorganic membranes for hydrogen separation and purification in a catalytic membrane reactor.
Palladium membranes have been identified as the membranes of choice in hydrogen separation and purification processes due to their infinite selectivity to hydrogen when defect-free. Despite their potentials in hydrogen processes, palladium membranes pose challenges in terms of cost and …

Direct synthesis gas conversion to alcohols and hydrocarbons using a catalytic membrane reactor.
In this work, inorganic membranes with highly dispersed metallic catalysts on macroporous titania-washcoated alumina supports were produced, characterized and tested in a catalytic membrane reactor. The reactor, operated as a contactor in the forced pore-flow-through mode, was used for the …

Studies of the Ethanol Steam Reforming Reaction in a Membrane Reactor
The subject of this dissertation is advanced inorganic membranes and their application in membrane reactors (MRs). The reaction studied is the ethanol steam reforming (ESR) reaction using Co-Na/ZnO catalysts, chosen because of their high activity and stability. The Co-Na/ZnO catalysts were prepared …

Functionalized Single Walled Carbon Nanotube/Polymer Nanocomposite Membranes for Gas Separation and Desalination
Polymeric membranes for gas separation are limited in their performance by a trade-off between permeability and selectivity. New methods of design are necessary in making membranes, which can show both high permeability and selectivity. A mixed matrix membrane is one such particular design, which …
