USE FRACTIONS FROM FLUID CATALYTIC CRACKING FOR DIESEL FUEL PRODUCTION

Popis výsledku v původním jazyce

Straight run gas oil (SRGO) and its mixtures with 5, 10, 15 and 20 wt% of light cycle oil (LCO) from fluid catalytic cracking (FCC) were hydrotreated on a commercial NiMo/Al2O3 catalyst in a laboratory flow reactor. Hydrotreating of the raw material was done at temperature of 350 oC, 4.0 MPa pressure, a weight hour space velocity of 1.0 h-1 and hydrogen to raw material ratio of 240 m3 BULLET OPERATORm-3. LCO had a high density due to a high content of bicyclic aromatics, and high content of sulphur species which are difficult to desulphurize. Therefore, increasing content of LCO in raw material resulted in increasing density and increasing content of sulphur and polycyclic aromatics in hydrotreating products. In order to improve some properties, mixtures of selected products with refined kerosene were prepared. The addition of kerosene decreased cold filter plugging point (CFPP) only about 1 - 2 oC. It was necessary to add depressant in an amount of 600 mgBULLET OPERATORkg -1 to achieve cold filter plugging point of -20 oC. Some refined products were blended with desulphurized heavy naphtha from FCC. The addition of heavy naphtha was limited mainly by its density. A mixture containing up to 10 wt% of the heavy naphtha and a mixtures with addition of 20 wt% of kerosene and up to 15 wt% of the heavy naphtha met the requirements of EN 590. Unsatisfactory CFPP values of winter blends could be resolved by depressant.
