Abstract
|
|
|
|
The desorption characteristics of NaY zeolite, of which Si/Al ratio is 2.36, was measured at 25℃ and 150℃ so as to be used practically as a adsorbent for separation of sulfur oxides from flue gas, for which adsorption and desorption cycles at 25℃ were repeated four times and that at 150℃ was done one time. As a result it took 30.8 at 150℃ and 164.1 minutes in average at 25℃ to reach equilibrium condition. It means that regeneration of the NaY zeolite can be done below 150℃ so that zeolite can be used for flue gas desulfurization.
