摘要：

作者选用催化原料油-减压蜡油为萃取剂,对催化裂化含酚废水进行脱酚预处理。结果表明,进水pH≤ 9. 5不加调节,温度t≥ 60℃,酚萃取脱除率达到90%以上。萃取后的减压蜡油依据现有工艺而进入催化裂化,不需进行再生等后处理。整个萃取工艺简单易行,完全能满足预处理的要求。

Abstract:

FCC raw material oil-decompressed wax oil is used as extraction agent to pretreat FCC phenol-bea ring was tewater.The rsults showed, under the conditions of pH≤ 9. 5and T≥ 60℃, the extraction removal rate is more than 90%. The extracted FCC raw material oil-decompr essed wax oil is car ried to FCC unit and doesnot need to be regenerated. The extraction technology is easy too perate and can meet the need of the pretreatment.

Key words: FCC, phenol-bearing wast water, extraction, decompressed waxoil
