CREATION OF NEW COMPOSITE MATERIALS FORHYDROGEN ENERGY PURPOSES. I. NEW LINESOF MEMBRANE PRODUCTION TECHNOLOGY

摘要

One of the main problems of hydrogen energy is separation and purification ofhydrogen produced by various conversion methods from raw hydrocarbons. Carbonmembranes can become real alternative both to inorganic and polymeric ones and enlargepossibilities of membrane methods of gas separation. Investigations aimed at the creationof composite carbon membranes suitable for operation at high temperatures in thepresence of organic vapors, in acid or alkaline (non-oxidizing) medium are presented.Our approach is based on the carbonization of polymeric layers on the porous inorganichigh temperature supports with definite structure which opens up new possibilities forcarbon nanostructure production. Main trends of future developments of compositecarbon gas separation and filtration membranes are also discussed.
