Renewable Diesel Production by Co-processing of Rapeseed
Oil Mixed with Straight Run Gas Oil

Abstract:

The research study presents the sequential co-processing of rapeseed oil and straight run gas oil mixtures by hydrotreating (HDT) and hydroisomerization (HYD) as source of hydrocarbon-based biodiesel. The feedstocks are the mixtures of straight run gas oil with 5%, 10% and 15% rapeseed oil. The hydrotreating experiments were performed in a micropilot laboratory flow reactor over a commercial NiMo/-Al2O3 catalyst at 350°C, 50 bar pressure, space velocity (LHSV) of 1h”-1 and H2/feedstock ratio of 1000 cm3/cm3. The hydrotreated products was subject to the HYD process in the same micropilot plant, over Pt- ZrO2 sulphated/Al2O3 catalyst at 250, 280°C, 30 bar pressure, LHSV of 1h-1 and H2/feedstock ratio of 800 cm3/cm3. The co-processing by HDT and HYD of straight run gas oil and rapeseed oil mixtures produce biodiesel with physico-chemical properties which respect EN 590 quality standard. Keywords: hydroisomerization, hydrotreating, rapeseed oil, pour point, viscosity
