The optimal preparation conditions of Mo/H-ZSM-22 bi-functional catalysts were obtained via the sublimation phenomenon of MoO₃ at high calcination temperatures, which was beneficial for the well-dispersion of MoO_x species with 5−10 nm particles. High reduction temperature enhanced the reduction from Mo⁶⁺ to Mo⁴⁺ and even from Mo⁴⁺ to Mo°, which would be beneficial for iso-alkanes formation with higher carbon reservation. Importantly, 89.3 % selectivity of C₁₆ alkanes of which 61.7 % were iso-C₁₆ alkanes were obtained with complete deoxygenation of palmitic acid, which was the highest selectivity of C₁₆ alkanes over Mo/H-ZSM-22 bi-functional catalyst prepared at a calcination temperature of 550 °C and at a reduction temperature of 600 °C. The results would offer a novel candidate of bi-functional catalysts for upgrading of microalgae-based bio-oil to high-value jet fuel components with high selectivity of iso-alkanes and carbon reservation.

Mo / H-ZSM-22双功能催化剂的最佳制备条件是通过在高煅烧温度下MoO ₃的升华现象获得的，这有利于MoO _x物种在5-10 nm颗粒之间的良好分散。较高的还原温度提高了从Mo ⁶⁺到Mo ⁴⁺甚至从Mo ⁴⁺到Mo°的还原，这将有助于形成具有更高碳保留率的异烷烃。重要的是，在棕榈酸完全脱氧的情况下，获得了89.3％的C ₁₆烷烃选择性，其中61.7％是异-C ₁₆烷烃，这是C的最高选择性。在550°C的煅烧温度和600°C的还原温度下制备的Mo / H-ZSM-22双功能催化剂上的_16种烷烃。该结果将为双功能催化剂的新型候选物提供基础，以将基于微藻类的生物油升级为具有高选择性的异烷烃和碳保留能力的高价值喷气燃料组分。
