1. A process for the preparation of a support for a mineral membrane for separation procedures, which is resistant to high pressures and which is formed from a carbon-carbon composite material of a porous texture suited to that of the mineral membrane, the process being characterized by the following steps : - the carbon-carbon composite material which is formed by a cloth or a felt of carbon fibres of relatively small thickness is impregnated by a bonding agent formed by a carbonisable resin, - said material is shaped, - carbonisation of the bonding agent is effected, and - the porous texture is adjusted. |
