| 摘要 |
The invention concerns a process for the treatment of ventilation air containing malodorous gases, e.g., styrene, involving: 1. An adsorption step onto a hydrophobic zeolite containing, for example, platinum and/or palladium, 2. A combustion-desorption step wherein hot gases pass over the impregnated zeolite in order to desorb the gas, e.g., styrene and burn it on the zeolite, in which the zeolite is encased in small tetrahedral-shaped containers.
