Abstract
For production of gasoline-range branched hydrocarbon frombutanal, Pd catalysts supported on differentmetal oxides were applied. Among the prepared catalysts, Pd/ZrO2 showed the complete butanal conversion with the formation of C7-to-C9 branched hydrocarbon (75% yield). Additionally, the ratios of O/C and straight-chain to branched hydrocarbon (n-C/br-C) were found to be 0.005 and 0.17, respectively. This indicates that an adequate combination of Pd dispersion and amphoteric ZrO2 character promoted hydrodeoxygenation, C–C coupling and isomerization reactions. Consequently, both Pd dispersion and acid–base properties of supports are suggested to play a pivotal role in producing gasoline-range hydrocarbon at a high yield.
