The catalytic transformation of short-chain hydrocarbons to higher homologs is an important reaction. In general, the yield of the homologated product was found to be sensitive to the structure and chain length of parent hydrocarbon and partial pressure of hydrogen used in the reaction. The yield was found to increase with the CH/sub 2//CH/sub 3/ ratio in the n-alkanes, starting from ethane and propane, which showed little or no activity, and tending to an upper limit with C/sub 7/ to C/sub 9/ alkanes. In a previous study, the authors found that various impregnated reduced MoO/sub 3/ catalysts are active for ethane homologation, which presumably occurs via insertion of active surface species (CH/sub x/) into adsorbed ethene. This note reports the results of ethene homologation over the various supported MoO/sub 3/ catalysts. The catalyst supports used in this work were TiO/sub 2/, ZrO/sub 2/, SiO/sub 2/, SiO/sub 2/-Al/sub 2/O/sub 3/ (13.75% Al/sub 2/O/sub 3/), SiO/sub 2/-Al/sub 2/O/sub 3/ (28.61% Al/sub 2/O/sub 3/), and ..gamma..-Al/sub 2/O/sub 3/. 14 references.
