NOTE

  • In this subclass,
  • In this subclass, the following terms or expressions are used with the meanings indicated:
    • "in the presence of hydrogen" or "in the absence of hydrogen" mean treatments in which hydrogen, in free form or as hydrogen generating compounds, is added, or not added, respectively;
    • "hydrotreatment" is used for conversion processes as defined in group C10G 45/00 or group C10G 47/00;
    • "hydrocarbon oils" covers mixtures of hydrocarbons such as tar oils or mineral oils.
  • In this subclass, in the absence of an indication to the contrary, classification is made in the last appropriate place.
WARNING

  • The following IPC groups are not used in the CPC system. Subject matter covered by these groups is classified in the following CPC groups:
