In this thesis, we particularly focused on competitive sorption of polar/apolar gaseous mixtures on zeolites under microwave irradiations. In a first step, we precisely studied wave-material mechanisms occuring between an electromagnetic wave and an adsorbat-adsorbent couple by studying thier dieclectric properties. In a second step, co-sorptions under microwave on a bench test have been realised and analysed. They showed the real advantages that microwave can bring to tjis process. Then, a regeneration process have benn described with a pmutiphysic modelling and experimentally validated. A purification process of a humide gas flow loaded with an apolar VOC have been proposed. The case of toluene, as an apolar compound, has been experimentally treated. This process allows an efficient and selective recovery of water and toluene molecules. This process uses the sorption selectivity properties of several zeolites and their contrasted dielectric losses.
