HYDROPROCESSING OF AQUEOUS PHASE OF PYROLYSIS OIL OVER NiMo/Al2O3–SiO2 IN MICROCHANNEL REACTOR
SINOPSIS
Sulfided NiMo catalyst supported on mesoporous silica-alumina and coated in a microchannel reactor was studied for the hydroprocessing of aqueous-phase of bio-oil (BO) obtained from pyrolysis of de-oiled jatropha curcas seeds cake (JCC). The oxygen content of the dissolved organic compound in the aqueous phase was reduced to a trace amount after hydroprocessing. A clear organic hydrocarbon phase product obtained after hydroprocessing contained 5%–45% gasoline (< C9), 5%–60% kerosene (C9–C14), 15%–40% diesel (> C14), with 15%–65% alkanes, 0%–5% polyaromatic hydrocarbons (PAH), negligible cycloalkanes and aromatics, with 30%–75% unreacted and residues. Maximum hydrocarbon yield (~ 65%) was obtained at 648 K, 0.25 LHSV, and 70 bar, with 35% residues and PAH. The water obtained after hydroprocessing contained few organics (< 5%).
