Creation Of New Composite Materials For Hydrogen Energy Purposes. I. New Lines Of Membrane Production Technology
One of the main problems of hydrogen energy is separation and purification of hydrogen produced by various conversion methods from raw hydrocarbons. Carbon membranes can become real alternative both to inorganic and polymeric ones and enlarge possibilities of membrane methods of gas separation. Investigations aimed at the creation of composite carbon membranes suitable for operation at high temperatures in the presence 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 inorganic high temperature supports with definite structure which opens up new possibilities for carbon nanostructure production. Main trends of future developments of composite carbon gas separation and filtration membranes are also discussed.
