【 摘 要 】

Hydrodeoxygenation (HDO) reaction is a fundamental step for producing bio-oil from lignocellulosic biomass. One of the major components from biomass is lignin which can be hydrolysed into phenolic derivatives. Here, we reported the preparation of Ni-based metal catalysts with the variation of a metal oxide for HDO of phenol. The Ni loading for each metal oxides is 15% (w/w), supported on SiO2, ZrO2, and Al2O3. The XRD analysis showed that Ni metal was detected in the SiO2 support at 2θ = 44.26°, 51.72°, 76.5°; Ni in ZrO2 at 2θ = 44.55°, 51.9°, 76.4°; and Ni in Al2O3 at 2θ = 44.12°, 51.72°, and 76.78°. The catalytic test for HDO reaction was carried out in the autoclave oil batch reactor, heated for 2 hours at 200°C with H2 gas atmosphere. Based on GC-MS analysis, the reaction at 200°C usingNi-SiO2 gave the highest product conversion, that is 52.2% with the selective formation of 2-methyl-1-butanol (52.2%). On the other hand, the reaction using Ni/ZrO2 only produce 17.64% of the products with selective formation of cyclohexanone (35.35%). The result showed that products distribution is significantly affected by the type of the support.
