【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）on cracking products in a fixed bed reactor.The results indicated that the optimum reaction conditions are cracking temperature of 510 ℃,space velocity of 10.00 h^-1,and m（CaO）/m（Al₂O₃）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 ℃）of 3.1 mm²/s,the acid value of 4.1 mgKOH/g,and the oxygen content of 2.37%,resulting in calorific value of 44.79 kJ/g.更多还原
