Investigation of the production of high quality biogasoil from pre-hydrogenated vegetable oils over Pt/SAPO-11/Al2O3

Abstract A novel field of the catalytic application of Pt/SAPO-11 catalysts for the isomerization of pre-hydrogenated sunflower oils aiming the production of diesel fuel components is presented. Experiments were carried out over 0.2-1.0%Pt/ SAPO-11 catalysts at 280-380°C, 30-80 bar; LHSVs of 1.0-4.0 h –1 , H 2 /feed of 250-400 Nm 3 /m 3 . Results indicated that the yield of biogasoils obtained under favorable process conditions was >88%, the ratio of i -/ n -paraffins was 3.2-6.8, the cetane numbers were 79-85 units and the cold filter plugging point (CFPP) values were between –19– −16°C. These are excellent blend stocks of diesel fuels.
