【 摘 要 】

This study aimed to prepare KF/CaO catalyst with high catalytic activity that can be applied to produce bio-fuel from Cornus wisoniana oil. The KF/CaO catalyst was characterized by Brunauer-Emmett-Teller surface area (BET), XRD, scanning electron microscopy (SEM), and temperature programmed desorption (TPD). The chemical compositions of C. wisoniana oil and bio-fuel oil were analyzed by GC-MS. The effect of the catalyst preparation conditions on catalytic activity was investigated. The optimal process conditions for the KF/CaO preparation were KF loading rate of 40%, calcination temperature of 600 degrees C, and 4h calcination time. Under the optimum process conditions, the bio-fuel yield reached 82.7 and 65% bio-fuel yield was obtained after being reused nine times. The bio-fuel oil obtained by catalytic cracking has similar chemical compositions to petroleum-based diesel, which exhibited good fuel properties.
