CATALYTIC PERFORMANCES OF CaO/Al2O3 COMPOSITE IN CATALYTIC CRACKING OF SOYBEAN OIL FOR HYDROCARBON FUEL

Abstract

Abstract: The physical mixing catalyst CaO/Al2O3 was applied in soybean oil by catalytic pyrolysis for hydrocarbon fuel production. The single factor experimental method was used to investigate the effect of cracking temperature, mass space velocity, m (CaO) / m (Al2O3) ratio on cracking products in a fixed bed reactor. The results indicated that the optimum reaction conditions are cracking temperature of 510 °C, space velocity of 10.00 h-1, and m (CaO) / m (Al2O3) ratio of 2: 8. Under the optimal conditions, the liquid yield reaches 71.00%. The content of hydrocarbon in pyrolysis oil is over 80.96% with kinetic viscosity (20 °C) of 3.1mm2/s, the acid value of 4.1 mg KOH/g, and the oxygen content of 2.37%, resulting in calorific value of 44.79 kJ / g.

Key words: catalytic cracking, composite catalyst, soybean oil, fuel oil
