Wax esters (WEs) synthesized by Euglena gracilis are potential sources for alternative fuels because of their high productivity, recent success in mass cultivation, and low energy consumption in extraction. In this study, deoxygenation of Euglena WE and conversion to hydrocarbons in a catalytic cracking process under a hydrogen-free atmosphere was investigated using a residue fluid catalytic cracking equilibrium catalyst with enhanced hydrogen-transfer activity. The deoxygenation of Euglena WE proceeded more rapidly with higher H₂O selectivity than that of saturated triglycerides. This is because initial β-elimination of WEs produces saturated fatty acids and higher olefins; the higher olefins rapidly release hydrogen species during cracking, cyclization and aromatization, and the hydrogen species accelerate hydrodeoxygenation of the saturated fatty acids. Furthermore, the cracking of Euglena WE produced large amounts of paraffins and olefins instead of aromatics. Therefore, Euglena WE was confirmed to be a preferable feedstock for the catalytic cracking process for hydrocarbon fuel production.

Euglena gracilis合成的蜡酯（WEs）由于其高生产率，近期在大规模种植中的成功以及提取中的低能耗而成为替代燃料的潜在来源。在这项研究中，Euglena WE的脱氧和在无氢气氛下催化裂化过程中转化为碳氢化合物的研究使用了具有增强的氢转移活性的渣油流化催化裂化平衡催化剂。H ₂含量较高时，Euglena WE的脱氧反应进行得更快O的选择性比饱和甘油三酸酯高。这是因为WEs的最初β消除会产生饱和脂肪酸和高级烯烃。高级烯烃在裂解，环化和芳构化过程中迅速释放出氢，而氢则加速了饱和脂肪酸的加氢脱氧反应。此外，Euglena WE的裂解产生了大量的链烷烃和烯烃，而不是芳烃。因此，证实Euglena WE是用于烃类燃料生产的催化裂化工艺的优选原料。
