Abstract

Graphical abstract: Highlights: DIPE production via 2-propanol dehydration using Fe. Modified alumina to pH 3, 6 and 12 as support of Fe and Cu oxides. Physical characterization of the catalysts by EDS, BET, XRD and HRTEM. Abstract: In this work, we studied the DIPE (C6 H14 O) production as an oxygenated compound from the catalytic performance of Fe and Cu oxides supported over alumina, on the 2-propanol dehydration reaction. The impregnation acidity effect was investigated. Samples at acid, moderately acidic, and basic pH were prepared. They were tested at 250 °C in a pilot micro-plant at atmospheric pressure. Catalytic results concluded the Fe3 O4 /γ-Al2 O3 impregnated to an acid pH showed the highest selectivity toward DIPE with adequate activity. All the catalysts at basic pH showed a complete selectivity to propylene (C3 H6 ). The yield of DIPE on the acidity reflects that is a linear function, which is valuable for a more rational design of new catalysts. The catalysts were characterized by adsorption-desorption of N2, X-ray diffraction, high-resolution transmission electron microscopy, and energy dispersive X-ray spectroscopy. The correlation between the textural and morphological properties of our catalysts and their catalytic activity was discussed.
