Santamaria and coworkers (Aguado cf a/.,2005) preparedPt/ZSM-5 membrane reactors for the combustion of n-hexane present at a low concentration in the air. Experimental results showed that n-hexane combustion was achieved at 210°C. A comparison of the conversion of the hexane obtained using the membrane reactor and the fixed bed reactor evidenced the better performance of the membrane reactor with a light-off temperature lower (about 70°C) than that obtained in the fixed bed reactor as illustrated in Fig. 6.5. Another example of the successful application of a Pt/ZSM-5 membrane in the catalytic combustion of volatile organic compounds (VOCs) (Bottino et al, 2001) showed that a high removal efficiency of toluene can be obtained and that the zeolite membrane with a relatively thick layer (40 pm) is clearly affected by mass transfer limitations.
