The catalytic transformation of ethane to propane is considered to be one of the useful reactions of alkane homologation. In a previous study of ethane homologation on reduced MoO/sub 3/ supported on SiO/sub 2/ and SiO/sub 2/-Al/sub 2/O/sub 3/, the reaction was found to occur via (i) dehydrogenation of ethane to ethylene, (ii) homologation of ethylene to propylene, and (iii) hydrogenation of propylene to propane. The active surface species (CH/sub x/) was assumed to be involved in step (ii) and play a key role in the homologation. It was found that molybdenum species on the supported catalysts are the active sites for the reaction but that catalytic activity seemed to show a dependence on the nature of the support. In this note, the authors report the results of ethane homologation on various supported reduced MoO/sub 3/ catalysts and their characterization by X-ray photoelectron spectroscopy. Supports used in this work were ZnO, TiO/sub 2/, ZrO/sub 2/, SiO/sub 2/, ..gamma..-Al/sub 2/O/sub 3/, SiO/sub 2/-Al/sub 2/O/sub 3/ (28.61% Al/sub 2/O/sub 3/) and SiO/sub 2/-Al/sub 2/o/sub 3/ (13.75% Al/sub 2/O/sub 3/). 9 references.
