Fischer-Tropsch synthesis using iron supported on potassic LTL zeolite and modified with Cs
Iron catalysts, to be used in the Fischer–Tropsch reaction were prepared using zeolite LTL and zeolite LTL modified with cesium, as supports. X-ray diffraction, specific surface area, atomic emission and absorption spectroscopies, Mo¨ssbauer spectroscopy in controlled atmosphere, between room temper...

| Sumario: | Iron catalysts, to be used in the Fischer–Tropsch reaction were prepared using zeolite LTL and zeolite LTL modified with cesium, as supports. X-ray diffraction, specific surface area, atomic emission and absorption spectroscopies, Mo¨ssbauer spectroscopy in controlled atmosphere, between room temperature and 22 K, H2 chemisorption and volumetric oxidation were used to characterize the solids. Comparing both catalysts, the Cs presence generates a solid with a lower reducibility degree and a lower quantity of Fe0 microcrystals inside the pore structure, leading to a lower activity per gram and a higher olefins/paraffins ratio. |
