METHOD AND DEVICE FOR REMOVING OXIDIZING POLLUTANT FROM GAS* PARTICULARLY* AIR

摘要

The method comprises: a) conducting the polluted gas (e.g. air) at a temperature of from 0 to 250 DEG C through a bed of particulate adsorbent- catalyst which adsorbent-catalyst comprises an adsorbent which has a high specific internal surface area and is impregnated with a material active at elevated temperature as an oxidation catalyst; and b) at intervals regenerating the said adsorbent-catalyst by increasing the temperature to a temperature of from 250 to 350 DEG C whereby the catalytic oxidation of the contaminating material accumulated on and in the said adsorbent catalyst is initiated. Apparatus for performing the above method is also described.
