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

摘要

The research study presents the sequential co-processing of rapeseed oil and straight run gas oil mixtures by hydroteating (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 350X, 50 bar pressure, space velocity (LHSV) of 1h"' and H2/feedstock ratio of 1000 cm~3/cm~3. The hydrotreated products was subject to the HYD process in the same micropilot plant, over Pt- ZrO2 sulphated/M2O3 catalyst at 250, 280°C, 30 bar pressure, LHSV of lh' and H2/feedstock ratio of 800 cm~3/cm~3. 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.
