摘要：
SO2 was adsorbed, oxidized, hydrated, and recovered continuously as aq. H2SO4 at 30-100-degrees-C on a polyacrylonitrile based active carbon fiber (PAN-ACF-FE-300). SO2 of 1000 ppm in a model flue gas was removed completely for longer than 60 h at 30 and 50-degrees-C by W/F=5.0 x 10(-3) g min ml-1 by supplying sufficient humidity of 10 and 20 vol%, respectively. The heat-treatment of the ACF at 800-degrees-C was found very effective to enhance the catalytic activity.
