<P>PROBLEM TO BE SOLVED: To provide a polysulfone-based hollow fiber membrane for CO<SB>2</SB>collection capable of separately collecting CO<SB>2</SB>. <P>SOLUTION: This polysulfone-based hollow fiber membrane for CO<SB>2</SB>collection satisfies at least one of the following requirements: (a) pure water permeation speed is 1×10<SP>-6</SP>m<SP>3</SP>/(m<SP>2</SP>×s×kPa) or more; (b) an average hole diameter present from an external surface to an internal surface is 0.005-0.1 μm; (c) an internal diameter is 1.0 mm or more; (d) distribution of fine holes inside the membrane is uniform. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
