CARBON MEMBRANES FROM CELLULOSE ESTERS |
摘要 |
A process for the production of a carbon hollow fibre membrane comprising: (i) dissolving at least one cellulose ester in a solvent to form a solution; (ii) dry/wet spinning the solution to form hollow fibres; (iii) deesterifying said hollow fibres with a base or an acid in the presence of an alcohol; (iv) if necessary, drying said fibres; (v) carbonising the fibres; (vi) assembling the carbonised fibres to form a carbon hollow fibre membrane. |
