摘要: 采用酸处理工艺对FCC催化剂废渣进行改性处理,考察了不同酸种类、酸量、固液质量比、温度、反应时间、搅拌速率对改性效果的影响,同时对改性前后催化剂废渣样品进行了XRF、FT-IR表征分析及孔结构测定,并将改性后的样品用于补充精制润滑油基础油。结果表明,FCC催化剂废渣经酸改性后,孔道结构得到明显改善,酸性位增多,对润滑油补充精制具有显著效果,可以代替白土作为润滑油基础油补充精制材料。最佳改性工艺条件为:盐酸质量分数14%,固液质量比1:2,改性时间2 h,改性温度95 ℃,搅拌速率100 r/min, N2保护。

Abstract: The residue produced during FCC catalyst manufacture process was modified by acids to prepare a lube based oil finishing material. The modification effect of acid type and quantity, temperature, liquid to solid mass ratio, reaction time and stirring rate was investigated. The properties of the samples before and after modification were characterized by means of XRF, FT-IR and the pore structure pattern was also determined by BET method. The results reveal that the pore structure of the treated residue is improved significantly and the number of acid site increases clearly. The modified FCC catalyst residue has a positive effect on lube oil finishing process, can replace clay as a finishing material. In addition, when HCl acid is used as the modifier, the most remarkable result appears at the modification conditions: 95℃, 2h, liquid to solid mass ratio of 2/1, stirring rate of 100r/min and under N2 protection.
