50.カキ殻を利用した高性能H_2S吸収剤の開発 : CaSO_4のH_2S吸収速度増加に及ぼす影響

抄録

In order to solve the interaction of Fe_2O_3 and CaSO_4, CaSO_4-loaded Fe_2O_3 was prepared. H_2S breakthrough curve was observed with a fixed-bed reactor equipped with quadrupole mass spectrometer (Q-mass). Although H_2S concentration in exit gas was detected about 30ppm in Fe_2O_3, H_2S concentration in exit gas was controlled about a few ppm in Fe_2O_3/CaSO_4.
