摘要
研究了双氧水和活性白土联合使用对潲水油脱色效果的影响,分析了吸附和氧化两种方法各自的影响因素。确定了潲水油的最佳脱色条件为:潲水油中加入3.5%(占油质量)的双氧水,60℃下搅拌反应20 min;再加入5%的活性白土,维持温度60℃不变,搅拌25 min可以达到理想的脱色效果。
The hogwash oil bleached by hydrogen peroxide and activated bleaching earth was studied. Effect factors of bleaching by adsorption and oxidation were analyzed. The idea bleaching effect could be obtained when the hogwash oil was bleached for 20 min at 60 ℃ with hydrogen peroxide under the conditions of hydrogen peroxide dosage 3.5 % （ based on the hogwash oil weight）, then was treated for 25 min at 60 ℃ with activated bleaching earth （dosage 5 %, based on the hogwash oil weight）.
