A circular rotating body having a plurality of fan-shaped blocks is disposed inside a casing and driven to rotate. A gas absorption/releasing material in the blocks absorbs/releases a specific gas component from a gas mixture depending on temperature. The rotating body has a hollow static central portion which is divided to form two temperature adjusting fluid paths through which temperature adjusting fluids having different temperatures pass. First and second independent gas flow paths are defined by the casing. A gas mixture containing the gaseous component flows along the first gas flow path through blocks which are heated to a first temperature at which absorption takes place. The blocks are then rotated to a position wherein they are heated to a higher second temperature and release the gaseous component which is exhausted via the second gas flow path. Blocks sequentially enter positions which separate the two different zones.
