Title:
HOLLOW FIBER CARBON MEMBRANE MANUFACTURING METHOD, HOLLOW FIBER CARBON MEMBRANE, AND MODULE THEREOF
Document Type and Number:
Japanese Patent JP2018083135
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method capable of stably manufacturing a carbon film compatible for both high permeability and high selectivity when the carbon film is used as a separation membrane of a mixture.SOLUTION: A hollow fiber carbon membrane manufacturing method of the invention comprises: the step of discharging a dissolved polyphenylene oxide at a temperature of temperature induced phase separation point or higher from an outer pipe of a double pipe structure nozzle, and discharging nitrogen gas from an inner pipe thereby to form a hollow yarn; and the step of bringing only the outer surface of the hollow yarn substance coagulated, into contact with a sulphur-containing compound containing liquid, thereby to add sulphur-containing compound.SELECTED DRAWING: None
