为综合利用含氧生物油制备生物柴油，制备了一种新型非硫Ni、Mo双金属催化剂。以硬脂酸转化率为目标，优化了 n（Ni）∶n（Mo）、金属负载量及载体类型等影响因素。结果表明，当n（Ni）∶n（Mo）=7∶3、金属负载量为25%、载体m（γ-Al₂O₃）∶m（β-分子筛）为3∶2时，硬脂酸转化率为93.70%，烷烃的选择性达95.44%。同时考察了含氧生物油在十二烷和供氢剂四氢萘中的产物分布及组成变化。

A new type of non-sulfur Ni/Mo bimetallic catalyst is prepared for the synthesis of biodiesel from oxygen-containing bio-oil.Taking the conversion rate of stearic acid as the object,the influencing factors are optimized,including the molar ratio of Ni to Mo,the loading amount of metals and carrier type.It is shown that the conversion rate of stearic acid reaches 93.70% and the selectivity of alkane reaches 95.44% when the molar ratio of Ni to Mo is 7∶3,the loading amount of metals is 25% and the mass ratio between γ-Al₂O₃ and β-molecular sieve is 3∶2.The products distribution and composition changes of the products in dodecane and tetralin are also discussed.
