Abstract:

SBA-16, HPW supported Pt-Ni bimetallic catalysts were synthesized by co-impregnation method. On SBA-16 support finely dispersed metal oxides can be found in the external surface of mesoporous channels. Their interaction is favoured to form Pt(2.0)-Ni(8)/10wt% HPW-SBA-16 catalysts showed enhanced catalytic activity and stability. The goal of this study Pt-Ni/HPWSBA- 16 was examined as a catalyst for the catalytic hydrodeoxygenation (HDO) of ?-tetralone, which is a model compound derived from lignocellulosic biomass. 93.24% and 96.43% of Cis and Trans-decalin was obtained at various reaction conditions. Effect of the metal weight percentage of Pt(2)/10wt% HPW-SBA-16, Ni(8)/10wt% HPW-SBA-16 and bimetallic Pt(0.5)- Ni(8)/10wt% HPW-SBA-16, Pt(1.0)-Ni(8)/10wt% HPW-SBA-16, Pt(1.5)-Ni(8)/10wt% HPW-SBA-16, Pt(2.0)-Ni(8)/10wt% HPW-SBA-16, reaction temperature (250-450�C), time (3-24h), hydrogen pressure (50 mL/min) and WHSV-1.89h-1 on conversion and selectivity were investigated systematically. The physiochemical properties of these catalysts were surveyed by BET, XRD, H2- TPR, H2-Chemisorption, NH3-TPD, HR-TEM EDS, XPS, FT-IR, DRS-UV and ICP-OES techniques. Hydrodeoxygenation of ?-tetralone into jet-fuels synthesis over the catalyst was tested in a fixed bed reactor, especially those that facilitate the removal of a ketone fragment. Standard HDO conditions permit both ketone reduction and C-O bond cleavage. The major products from HDO of ?-tetralone for the active bimetallic catalysts were jet fuel hydrocarbons such as ?-tetralol, cis/trans-decalin and tetralin. The removal of oxygen is evidenced by the production of tetralin and cis/trans-decalin.
