摘　　要：以蓖麻油脱色后的废白土为原料,利用自行设计制造的专业提油设备,采用6#溶剂浸出工艺回收废白土中的油脂.研究了作业温度、萃取次数等因素对浸出效果的影响.研究结果表明:该工艺操作稳定,回收的油脂通过精炼可达到国际1#蓖麻油标准,脱油后的废白土残油量小于5%.With the raw material of spent bleaching clay of castor oil refining, castor oil was recovered by 6^# solvent extraction with special equipment designed and manufactured by oneself. The effect of the temperature and the solvent extraction times on the solvent extraction result were also discussed. This operating technology is very steady. Through reclamation, the quality of recovered castor oil has reached the ICOA-1^# castor oil criterion. The residual castor oil in the spent bleaching clay is less than 5 ^# after recovering castor oil.
