摘要：

采用水热法合成了Co–ZnO复合纳米线，通过改变NaOH浓度考察其对Co–ZnO复合纳米线结构和形貌的影响，并用等体积浸渍法负载金属Ni，制备反应吸附脱硫剂。以正庚烷/噻吩为模拟油，在反应温度为320 ℃、压力0.6 MPa、进料的体积空速为6 h–1及氢油体积比为100:1的条件下，考察了复合型钴锌纳米线负载镍脱硫剂、负载型镍钴锌脱硫剂和无钴添加负载型镍锌脱硫剂的脱硫性能。结果表明：NaOH浓度为1 mol/L时制备的Co–ZnO复合纳米线有良好的纳米形貌，负载活性组分Ni后脱硫效果最好；复合型钴锌纳米线负载镍脱硫剂中Co掺杂比负载型脱硫剂更均匀，Co掺杂使氧化态的Ni变得容易还原，相同条件下可以得到更多的活性位，进而有利于脱硫剂脱硫，其脱硫性能明显高于负载型镍钴锌脱硫剂和无钴添加负载型镍锌脱硫剂，达到93% (质量分数)以上。
