METHOD AND APPARATUS FOR THE PURIFICATION OF WASTE GAS CONTAINING GASEOUS POLLUTANTS Abstract of the Disclosure A process and apparatus for the purification treatment of a waste gas containing gaseous pollutants. The process comprises the steps of upwardly moving the waste gas through a tower, provided in the interior with a multiplicity of sub- stantially horizontal shelves, and at the same time downwardly moving activated carbon particles through the tower, allowing the waste gas and the activated carbon to come into contact with each other and permitting the activated carbon to form a fluidized bed on each of the shelves, thereby causing the gaseous pollutants of the waste gas to be adsorbed on the activated carbon and consequently effecting the removal of gaseous pollutants from the gas. The waste gas can be contin- uously purified and the activated carbon recycled. The carbon particles employed are activated carbon spheres and perforated plates having a weir formed thereon are used as the shelves.
