| Abstract: |
| Ni loaded in three zeolites (HZSM-5, Hbeta, HY) was used to catalyze the conversion of microalgae lipids into jet fuel range n-alkanes and aromatic hydrocarbons.The phases of Ni/HZSM-5, Ni/Hbeta and Ni/HY catalysts were identified by X-ray diffraction (XRD), and the redox characteristics of the catalysts were characterized by H2-TPR. The activity of the three catalysts was evaluated at 400 ℃,and the catalytic reaction temperature was optimized.The results showed that Ni was successfully loaded in the three zeolites,and NiO in Ni/HZSM-5 and Ni/Hbeta were more easy to be reduced,while NiO in Ni/HY was difficult to be reduced. Ni/HZSM-5 showed the best jet fuel range hydrocarbon selectivity,with total yield of jet fuel range n-alkanes and aromatic hydrocarbons 25.72%.When the reaction temperature was 420 ℃, the ratio of jet fuel range n-alkanes to aromatic hydrocarbons was the best in the liquid product with Ni/HZSM-5 as catalyst and the yields of n-alkanes and aromatic hydrocarbons were 17.25% and 16.40%，respectively. |
