CRACKING HYDROCARBON OILS; PRODUCTION OF LIQUID HYDROCARBON MIXTURES, e.g. BY DESTRUCTIVE HYDROGENATION, OLIGOMERISATION, POLYMERISATION (cracking to hydrogen or synthesis gas C01B; cracking or pyrolysis of hydrocarbon gases to individual hydrocarbons or mixtures thereof of definite or specified constitution C07C; cracking to cokes C10B); RECOVERY OF HYDROCARBON OILS FROM OIL-SHALE, OIL-SAND, OR GASES; REFINING MIXTURES MAINLY CONSISTING OF HYDROCARBONS; REFORMING OF NAPHTHA; MINERAL WAXES[6]

Note(s)
In this subclass:[3]groups C10G 9/00-C10G 49/00—are limited to one-step processes;————combined or multi-step processes are covered by groups C10G 51/00-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, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, classification is made in the last appropriate place
