VERFAHREN ZUR ENTFERNUNG VON HALOGENHALTIGEM GAS

The present invention provides a method for removing a halogen series gas, which has abilities of preventing heat generation of an adsorbent, having a high performance of treating a halogen series gas, reducing an odor of an adsorbent used and generation of a solid waste, and easily recognizing the end of reaction. A halogen series gas is removed by contacting a gas containing a halogen series gas forming at least one kind selected from the group consisting of HF, HCl, HBr and HI by water with a granule containing from 60 to 99.9 mass% of a solid base and from 0.1 to 40 mass% of a carbonaceous material to the total mass amount of the granule in the presence of water. The solid base is preferably sodium hydrogencarbonate, and the carbonaceous material is preferably an activated carbon having an average pore radius of from 0.1 to 50 nm and a pore volume of from 0.05 to 4 cm /g.
