The Comparison of Co, Ni, Mo, CoMo and NiMo Sulfided Catalysts in Rapeseed Oil Hydrodeoxygenation.
Original language description
The Al2O3 supportedmonometallic Co, Ni andMoand bimetallic CoMo and NiMo catalysts were compared in rapeseed oil hydrodeoxygenation (HDO) reaction after in situ sulfidation. The reaction was described by five pseudo-first order rate constants (k1–k5) for the simplified reaction scheme: triglycerides (Tgs) to octadecane (k1), Tgs to oxygenates (Oxs, i.e., sum of fatty acids, fatty alcohols, and esters of fatty acids and fatty alcohols) (k2), Tgs to heptadecane (k3), Oxs to octadecane (k4), andOxs to heptadecane (k5). The empirical pseudo-first order rate constant of the hydrocarbons (Hcs) product formation (kHc) increased in the order Ni/Al2O3 * Co/Al2O3CoMo/ Al2O3 * Mo/Al2O3 _ NiMo/Al2O3 showing hence a significant synergy between Ni and Mo. All monometallic catalysts exhibited k1 and k3 practically zero and the reaction proceeded essentially through the formation of the oxygenated reaction intermediates (high k2). The Co/Al2O3 and Ni/Al2O3 catalyzed selectively hydrodecarboxylation (HDC) of fatty acids (high k5). OverMo/Al2O3, theHDOpathway, however, was nearly the exclusive one (high k4). CoMo/Al2O3 and NiMo/Al2O3 catalysts yielded both HDO and HDC products suggesting partial synergy in the relative selectivity HDO/HDC between Co(Ni) and Mo.
