| titleOfInvention | Activated carbon hollow fibers and manufacturing method of it with absorbent radioactive cesium |
| abstract | The present invention relates to a method for producing a hollow activated carbon fiber for radioactive cesium adsorption. The method for producing a hollow activated carbon fiber for adsorption of radioactive cesium of the present invention comprises: a pretreatment step of heat-treating petroleum residue in a nitrogen atmosphere at a temperature of 340° C. and stirring at a stirring speed of 150 rpm for 6 hours to remove volatile oil; a melt spinning step of melt spinning the pretreated raw material to form a hollow; stabilizing the melt-spun raw material by staying at a temperature of 220 to 280° C. for 6 hours in an oxygen atmosphere to aromatize the spun fiber; a carbonization step of carbonizing the stabilized fiber while injecting nitrogen gas into an electric furnace to produce a hollow activated carbon fiber; and an impregnation step of impregnating the hollow activated carbon fiber with Prussian blue to impart adsorption performance to radioactive cesium ions. According to the present invention, Prussian blue is used to adsorb radioactive cesium, but by providing hollow activated carbon fibers as a carrier of cesium, the adsorption performance can be further increased, and in particular, petroleum residue that is cheaper than PAN A process for manufacturing a hollow activated carbon fiber with excellent radioactive cesium adsorption performance as a raw material is provided. More specifically, after heat-treating a residual oil such as PFO in a low-viscosity state to increase the viscosity, remove volatile oil, and melt-spinning , stabilizing in an oxygen atmosphere to proceed with the aromatization of the fiber, and carbonization at a specific temperature to prevent the fusion phenomenon from occurring and to maintain the shape of the fiber. |
