摘要
碱渣碳化液最突出的问题之一是酚的脱除。通过对比实验 ,选择了适合于碳化液弱碱性环境的高效、高萃取容量的络合萃取剂 3 0 %TBP煤油溶液。该萃取剂在pH值为 8.5的弱碱性条件下单级萃取脱酚率仍高于99%。
Based on comparison tests,a complex extractor,30% TBP kerosene solution with high extraction power and suitable to carbonized weak caustic ambient was selected.Under weak caustic conditions of pH 8.5,the percent of single-stage extraction dephenol is higher than 99%.
