77.高性能フェライト系硫化水素吸収剤の開発

抄録

To improve performance of absorbent, zinc ferrite was prepared on an activated carbon fiber and an activated carbon with high specific surface area. Absorption behavior of ACF- and AC-loaded zinc ferrites for hydrogen sulfide was investigated using a thermogravimetric analyzer (TGA). Specific surface area of ACF- and AC-loaded zinc ferrites prepared here ranged from 76 to 1190m^2/g. Absorption rate of these zinc ferrites became large as specific surface area increase, and reached about centuple as compare to that of zinc ferrite prepared by dry process.
