Abstract: A rotary gas treating apparatus has a front-stage rotor and a rear-stage rotor each consisting essentially of an adsorbent material and allowing gas flow along a rotational axis. These rotors have, within respective rotational areas thereof, adsorbing areas for introducing a treatment-object gas and desorbing areas for introducing a recycling gas. The adsorbing area of the front-stage rotor and the adsorbing area of the rear-stage rotor are disposed in the mentioned order in a continuous treatment-object gas flow passage from an upstream side thereof. The desorbing area of the front-stage rotor and the desorbing area of the rear-stage rotor are disposed in recycling gas flow passages, respectively. With the invention, a revolving direction of the front-stage rotor and a revolving direction of the rear-stage rotor are reverse to each other. Further, the adsorbing material of the front-stage rotor has a greater average pore diameter than that forming the rear-stage rotor.
