Catalysis with Inorganic Membranes

MRS Bulletin, 1994
Catalytic inorganic membranes are among the most challenging and intriguing porous materials. Consisting of a thin film of mesoporous or microporous inorganic material deposited on a macroporous material, catalytic membranes are multifunctional materials that must be engineered for both chemical and physical properties.

Inorganic membrane reactors

Journal of Membrane Science, 1994
Abstract The availability of inorganic membranes which can withstand high temperatures has resulted in a wide ranging opportunity for the application of membranes in chemical reactors. Increased conversions, better selectivity, milder operating conditions and decreased separation load are some of the attractive features which are going to promote ...

Inorganic membranes and membrane reactors

Korean Journal of Chemical Engineering, 2001
The inorganic membrane reactor is a combined unit operation of chemical reactions and membrane separations. By having a membrane reactor, the downstream separation load can be reduced. Also, the yields can be increased and conversion can be improved for equilibrium limited reactions. However, many of the industrial chemical reactions take place at high

Studies with inorganic precipitative membranes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1977
Abstract Effective fixed charge densities of parchment-supported cobalt and nickel phosphate membranes in contact with various 1: 1 electrolyte solutions have been evaluated from membrane potential measurements. The methods used for the estimation of charge densities were: (a) Teorell—Meyer—Sievers; (b) two different methods of Kobatake et al.; and ...

Functional organic–inorganic hybrid membranes

Chemical Engineering and Processing: Process Intensification, 2008
Abstract The membrane selectivity may be induced either by carrier molecules or by transmembrane channels. From the mechanistic point of view, we use carriers which self-assemble in functional aggregates which would present combined (hybrid) intermediate features between the former carrier-monomers and the resulted channel-forming superstructures ...

Porosimetric Characterization of Inorganic Membranes

Separation Science and Technology, 1994
Abstract This paper deals with the evaluation of pore size and pore size distribution of inorganic membranes by liquid-liquid displacement porometry. Carbon and ceramic membranes were tested with a fully automatic porometer, and different results were obtained depending on the type of membrane.
