Stabilization of hydrocracked lubricating oils

  title={Stabilization of hydrocracked lubricating oils},
  author={T. Y. Yan},
Research directed to finding an effective and less expensive method for stabilizing hydrocracked lubricating oils is reported. It is noted that hydrocracked lubricating oils are unstable and form sediment upon exposure to light and air. These unstable oils can be made indefinitely stable by treatment with olefins over acidic catalysts. The reaction involved in this treatment is aromatic alkylation, possibly including the reactive materials in the oil. Acidic catalysts are effective for this… CONTINUE READING
