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.
L'invention porte sur un procédé pour la fabrication d'une membrane en fibre creuse de carbone comprenant : (i) la dissolution d'au moins un ester de cellulose dans un solvant pour former une solution ; (ii) le filage à sec/humide de la solution pour former des fibres creuses ; (iii) la désestérification desdites fibres creuses avec une base ou un acide en présence d'un alcool ; (iv) si nécessaire, le séchage desdites fibres ; (v) la carbonisation des fibres ; (vi) l'assemblage des fibres carbonisées pour former une membrane en fibre creuse de carbone.
