Modification by SiO2 of Alumina Support for Light Alkane Dehydrogenation Catalysts, Giyjaz E. Bekmukhamedov, Aliya N. Mukhamed?yarova, Svetlana R. Egorova and Alexander A. Lamberov, Catalysts 2016, 6, 162; doi:10.3390/catal6100162

Аннотация

Due to the continuously rising demand for C3?C5 olefins it is important to improve the performance of catalysts for dehydrogenation of light alkanes. In this work the effect of modification by SiO 2 on the properties of the alumina support and the chromia-alumina catalyst was studied. SiO 2 was introduced by impregnation of the support with a silica sol. To characterize the supports and the catalysts the following techniques were used: low-temperature nitrogen adsorption; IR-spectroscopy; magic angle spinning 29Si nuclear magnetic resonance; temperature programmed desorption and reduction; UV-Vis-, Raman- and electron paramagnetic resonance (EPR)-spectroscopy. It was shown that the modifier in amounts of 2.5?7.5 wt % distributed on the support surface in the form of SiOx-islands diminishes the interaction between the alumina support and the chromate ions(precursor of the active component).
