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

Description

C10G encompasses processes for converting and refining crude hydrocarbon feedstocks into usable liquid and solid products through thermal, catalytic, and chemical transformation methods. This includes cracking operations (thermal and catalytic), hydrogenation processes for destructive or non-destructive conversion, oligomerisation and polymerisation of lighter hydrocarbons, and recovery techniques for hydrocarbons from unconventional sources such as oil-shale, oil-sand, and associated gases. The subclass also covers refining and purification of hydrocarbon mixtures and naphtha reforming for octane enhancement, as well as production and refining of mineral waxes derived from petroleum. Related processing of lubricants and specialty hydrocarbon products fall under adjacent subclasses within C10.
