PREPARATION OF ADSORPTION-SELECTIVE ACTIVATED CARBON HOLLOW FIBER MEMBRANES

摘要

A manufacturing method of adsorption-selective activated carbon hollow fiber membranes is provided to offer superior energy efficiency, excellent mechanical strength, and high permeability also about compressive gas of low concentration. A manufacturing method of adsorption-selective activated carbon hollow fiber membranes comprises the following steps of: manufacturing a spinning solution by dissolving 5 ~ 30 weight% of a polymer resin including polyacrylonitrile and 5 ~ 30 weight% of pitch into 60 ~ 90 weight% of an organic solvent; manufacturing a hollow fiber membrane by performing a wet spinning process with water or a mixture of water and an organic solvent; oxidizing the heated hollow fiber membrane; carbonizing the hollow fiber membrane by rotating the membrane in a tube furnace; and activating the hollow fiber membrane by using nitrogen gas in the heated hollow fiber membrane.
