Fischer–Tropsch reaction on Fe/Zeolite-L system. Structure and catalytic behavior

Iron supported on potassic and acidic forms of commercial zeolite-L were used to determine the role played by the small metallic crystallites inside the zeolite channels and the increase of the acidity of the support on the activity and selectivity of the catalysts. The solids were characterized by...

Description
Summary:Iron supported on potassic and acidic forms of commercial zeolite-L were used to determine the role played by the small metallic crystallites inside the zeolite channels and the increase of the acidity of the support on the activity and selectivity of the catalysts. The solids were characterized by Mössbauer spectroscopy (MS), specific surface area (BET), X-ray diffraction (XRD), atomic absorption spectroscopy, CO and H 2 chemisorption and volumetric oxidation (VO). The solids thus obtained were used in the Fischer–Tropsch synthesis. About 15% of total Fe 0 remained inside the zeolite channel after reduction and they were active for the reaction.
