1.The denitrogenation effects are investigated for the vacuum cut 3 lube base oil from Daqing by using the organic acid modified activated clay FY?14 as adsorbent. The performances of activated clay and FY?14 adsorbent are compared.
2.By using FDW 10 catalyst in dydrogenation depression of freezing point of the tail oil under definite temperature and pressure in the lab, we got a distillation cut of the lube base oil with viscosity index more than 60. After clay treating, it fully accords with the lube base oil standards.
