Influence of Acid-Base Characteristics of Different Structural-Type Zeolites (FER, MFI, FAU, BEA) on Their Activity and Selectivity in Isobutanol Dehydration
Original language description
The different structural-type zeolites (FER, MFI, FAU, BEA) are investigated as catalysts in (bio)isobutanol conversion into linear butenes. The zeolites´ structure and morphology are confirmed by XRD, N2 (77 K) ad(de)sorption, SEM, EDX, XPS, and 27Al, 29Si, 1H MAS NMR, 1H-29Si CP MAS NMR. The nature and strength of acid-base sites are determined by FTIR spectroscopy of adsorbed pyridine, potentiometric titration, and TPD of NH3/CO2/H2O with MS control. The acid-base properties of the zeolites ' surfaces influence their catalytic properties in the target process. The higher selectivity towards linear butene isomers achieved over FER and MFI can be explained by the high strength and density of Bronsted acid sites (over 90 % of the total surface acidity). MFI might be regarded as a potential material for the creation of novel catalysts for isobutanol conversion into linear butenes at moderate temperatures (448-473 K) since it offers greater operating stability throughout the process.
