摘要： Malodorous gases such as amines, organosulfur compounds, hydrogen sulfide, styrene and aldehydes are economically and efficiently treated at ambient temperature and pressure by a catalytic absorption and oxidation process comprising: (a) bringing the malodorous gases into contact with a scrubbing water containing a heterogeneous catalyst to absorb the malodorous components catalytically, and (b) subjecting the resulting solution containing the malodorous components to a catalytic oxidation by contacting it with an oxidizing agent such as hydrogen peroxide, ozone, oxygen, air, nitrogen oxides, and NaOCl in the presence of the catalyst at a temperature ranging from 0 to 100 □ under an ambient pressure, the heterogeneous catalyst comprising an active metal element selected from alkali, alkaline earth and transition metals, and an oxide support material.
