Abstract:
The present invention disclosed a method for improving the adsorption capacity of a fixed bed and its application in organic waste gas treatment field. The method solved existing problems including high equipment investment cost, low processing capacity, attendant safety risks, etc. The steps are: (1) adsorption: organic waste gas is passed through the adsorption column containing the adsorbent to allow the organic waste to be adsorbed; when VOCs concentration at the outlet end of the adsorption column reached a preset value, the adsorption is halted; (2) desorption: adsorbent that has absorbed VOCs was desorbed by water vapor of 110° C. or higher, or hot nitrogen of 150° C. or higher; the desorbed VOCs enter into a condenser and is recovered in liquid state; (3) pre-adsorption of water: spray water inside the adsorption column after the desorption to adjust the water content of the adsorbent to 8-35%, no other treatment is necessary before the next batch of VOCs adsorption. The present invention can effectively reduce the bed temperature and improve adsorbent's adsorption capacity.

Claim (Index 7):
A method for improving the adsorption capacity of the fixed bed according to  claim 2 , as applied in the field of organic gas waste adsorption treatment, wherein the temperature increase in the fixed bed is reduced; and wherein the desorbing is performed by water vapor of 110\u00b0 C. or higher, or by hot nitrogen of 150\u00b0 C. or higher.
