Synthesis of hierarchical ZSM-48 nano-zeolites

Author affiliations


Hierarchical zeolites are known to offer fast mass transfer along with size and shape selectivity compared to their conventional micron-sized zeolite counterparts. We report here the successful synthesis and characterization of a hierarchical ZSM-48 zeolite (*MRE-type structure) using a specific gemini-type surfactant that acts as dual functions template to generate at the same time micropores and mesopores. The Si/Al molar ratio of the starting gel seems to influence the nature of the obtained zeolitic phase. Pure hierarchical ZSM-48 zeolites were only obtained at a high Si/Al molar ratio of the starting gel (Si/Al = 31 to 50). The catalytic properties of these acidic catalysts were then tested in ethanol transformation into hydrocarbons.
