Deodorization of stink gases in sewage farm of oil refinery through adsorption

Stink gases in sewage farm of oil refinery pollute environment and influence scent of people. Adsorbents can be used to deodorize the stink gases. The adsorbents selected through experiments have large sulfur capacity and long service life and can selectively absorb hydrogen sulphide and methyl mercaptan in waste gases. They can deodorize the stink gases under experimental conditions.
