Abstract:
Catalytic cracking of two different vegetable oils was performed in a continuous FCC pilot plant. Both palm and soybean oil were selected as feedstock. A commercial equilibrium catalyst was used. Experiments at cracking temperatures in the range of 430-550°C were conducted. At low temperatures liquid fuel products like gasoline and light cycle oil (LCO) are maximized. LCO can be used as diesel blend but contains large amounts of aromatics at usual process conditions. A 7-lump model was used for mass balances. Gas and gasoline fractions were analyzed in greater detail. Results in terms of quantity and quality were similar for both feedstocks. At 450°C soybean oil produces 10.1wt% gas, 45.1wt% gasoline and 17.8wt% LCO, whereas palm oil produces 11.4wt% gas, 43.6wt% gasoline and 15.7wt% LCO at 460°C. About two thirds of gas consists of olefins. A gasoline maximum occured at about 500°C. Gasoline aromaticity strongly decreased at lower temperatures resulting in low octane numbers. LCO yield increased. Coke stayed approximately the same at all operating conditions. Initial oxygen content in the feedstock was mainly converted into water. Carbon oxides were detected in small quantities.
