Conversion of Ethanol and Fusel Oils over Au–M/MFI/Al₂O₃ Catalysts

Chistyakova, P. A. / Chistyakov, A. V. / Nikolaev, S. A. / Bagdatov, R. A. / Tsodikov, M. V. / Heider, J. / Netrusov, A. I.

The present study investigates the regularities in the conversion of ethanol and water/ethanol mixtures in the presence of Au–M/MFI/Al₂O₃ modified zeolite catalysts, where M = Cu, Ni, and Pd. The conversion products of ethanol, fusel oils, and of a model ethanol/acetone/1-butanol (ABE) mixture were investigated in detail. Transmission electron microscopy (TEM) revealed that supported metal particles mostly aggregate into bimetallic clusters 8–15 nm in size. The variations in product selectivity were found to be caused by coking and, therefore, by a declining concentration of acid sites on the catalyst surface.
