NOTE
-
In this subclass,
- groups C10G 9/00 to C10G 49/00 are limited to one-step processes;
- combined or multi-step processes are covered by groups C10G 51/00 to C10G 69/00 ;
- refining or recovery of mineral waxes is covered by group C10G 73/00 .

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.
