Co /SBA-15催化氧化石蜡的研究

实验以52号石蜡为原料，采用Co /SBA-15为催化剂，用空气作氧化剂，对石蜡氧化进行了研究。考察了反应温度、反应时间、空气流量等工艺条件的影响。实验结果表明，Co2O3最佳负载量为15%，在氧化温度140℃、氧化时间5h、空气流量0.6L/min的最佳反应条件下可得到色泽浅、气味轻、酸值较高的氧化石蜡产品。

STUDY ON THE CATALYTIC OXIDATION OF PARAFFIN WAX OVER Co/SBA-15 CATALYST

Study on the oxidation of paraffin wax was carried out by using 52# wax as raw material, Co/SBA-15 as catalyst and air as oxidant. The effects of reaction temperature, reaction time and air flux on the oxidation of wax were investigated. The experimental results indicated that under the optimal reaction conditions of using a Co/SBA-15 catalyst with an optimal Co2O3 loading of 15%, an oxidation temperature of 140℃, an oxidation time of 5h and an air flux of 0.6 L/min, a high acid number, light color and less odor oxidized wax was obtained.
