摘要
对表面活性剂溶液回收炼油厂废白土中的石蜡和润滑油脱蜡脱油废白土的再生活化、综合利用进行实验研究。通过对表面活性剂的筛选及工艺条件最优化，使蜡和油的回收率分别达到９３％和９５％，再生白土的脱色效率优于新鲜活性白土。用脱蜡脱油废白土为原料制取的白炭黑和４Ａ沸石的质量均达到国家标准。
The experiments for wax and lube oil recovery from waste clay in oil refining industries by surfactant solutions,and for regeneration and comprehensive utilization of dewaxing or deoiling waste clay have been conducted. After sifting out the best surfactant and process,the recovery rate of wax and lube oil can reach 93% and 95% respectively. The decolorizing efficiency of regenerative waste clay is higher than that of fresh active clay, and the qualities of white carbon black and 4A zeolite made from dewaxing or deoiling waste clay conform to those of the standards.
