Hydroprocessing of lipids extracted from marine microalgae Nannochloropsis T 1. over sulfided CoMoP/Al2O3 catalyst

Authors: M.K. Poddar, M. Anand, S.A. Farooqui, G.J.O. Martin, M.R. Maury A.K. Sinha Abstract Hydroprocessing of neutral lipids extracted from Nannochloropsis sp. algal biomass was studied over sulfided cobalt molybdenum phosphorus/aluminium oxide (CoMoP/Al2O3) catalyst in a batch reactor at 300–375 °C with H2 at 50–120 bar. A clear light yellowish green product was obtained, containing 6–26% gasoline, 35 50% kerosene, 8–40% diesel, with 10–80% alkanes, 1–10% cycloalkanes, and 5–35% aromatics, with …
