Optimizing synthesis conditions and support type for structured PSA adsorbents

• Thin faujasite films were grown on porous and dense cordierite monoliths by hydrothermal treatment using a gel or a clear solution. A well defined FAU film with a thickness of about 1 μm could be grown on both supports using the gel. However, a relatively high weight gain after synthesis was recorded for the porous monoliths due to zeolite crystallization in the pores, which may be undesirable for PSA applications. The films grown in the clear solution consisted of both FAU and sodalite crystals and the thickness of the FAU film was about 0.5 μm. A 5 times lower weight gain was observed and much less zeolite grew in the pores of the support, which may be an advantage for PSA applications. The adsorption properties of the samples are currently under investigation.
