摘要
大庆高粘度和专用基础油通过深度脱氮以满足新氧化安定性标准，但该过程仍缺乏有效的补充精制工艺。对比白土精制、络合脱氮、临氢降凝－加氢精制三种方法后，推荐改造白土精制为络合脱氮的方法。
Deep denitrification on the high viscosity and special base oil from Daqing still lacks effetive finishing in meeting new standard of oxidation stability.Through contrasting the clay refining, complexing denitrification and HDW-HDT, showed it is a good way to use complexing denitrification instead of clay refining.
