摘　　要：从催化氧化石蜡生产特种蜡及其添加剂的角度出发,采用Co/SiO2、Co/MCM-41、Zr/MCM-41、Co-Zr/MCM-41为催化剂,用空气作氧化剂,对石蜡氧化进行了实验研究。考察了金属负载量对催化性能的影响、不同负载金属催化剂的石蜡氧化活性比较、Co、Zr含量对Co-Zr/MCM-41活性的影响。实验结果表明,以MCM-41作为载体制备钴负载量为12%、锆负载量为3%的复合氧化物为催化氧化反应的催化剂,在氧化温度为140℃、氧化时间为5 h、空气流量为0.7 L/min、催化剂用量为2%的最经济反应条件下可得到高酯酸比的氧化蜡产品。In order to produce special wax and its additives by the catalytic oxidation process, paraffin wax oxidation reaction was researched systematically by using Co/SiO2, Co/MCM-41, Zr/MCM-41 or Co-Zr/MCM-41 as catalyst and air as oxidant. Effects of metal loading amount on its catalytic performance were investigated as well as the performance of catalyst with different metal for catalytic oxidation of paraffin. Effects of Co and Zr contents on Co-Zr/MCM-41 activity were analyzed. The results show that, using Co-Zr/MCM-41 （12% Co, 3% Zr） as catalyst, under the conditions of the oxidation temperature 140℃, oxidation time 5h, air flow rate 0.7 L/min and catalyst 2%, oxidized wax with high ester/acid ratio can be obtained.
