Abstract:
Mesoporous molecular sieve SBA-16 supported PdNi bimetallic catalysts were synthesized by the co-impregnation method. PdNi/SBA-16 bimetallic Im3m mesoporous catalyst showed superior catalytic performance in the production of jet-fuel range hydrocarbons. Vapour phase hydrodeoxygenation of α-tetralone was carried out under ambient pressure and the highest selectivity (88.21%) for the isomerized product trans-decalin was obtained. PdNi impregnated on different mesoporous (MCM-41, SBA-15, KIT-6) and metal oxides (γ-Al2O3, CeO2, TiO2, ZrO2, SiO2) supports and the catalytic activity was compared with PdNi/SBA-16. Synergetic interaction between the Pd(111) and Ni(111) with increased total acidity enhanced the catalytic activity of PdNi/SBA-16. Among the bimetal, Nickel was found to be the most active metal for the complete reduction of aromatic ring, while Pd favoured the deoxygenation. The major products obtained from hydrodeoxygenation of α-tetralone were cis/trans-decalin, tetralin and α-tetralol.
