DIFF Subgroup
C10G 45/60

characterised by the catalyst used

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Refining of hydrocarbon oils using hydrogen or hydrogen-generating compounds > to change the structural skeleton of some of the hydrocarbon content without cracking the other hydrocarbons present, e.g. lowering pour point; Selective hydrocracking of normal paraffins > characterised by the catalyst used

CPC:

Refining of hydrocarbon oils using hydrogen or hydrogen-generating compounds > to change the structural skeleton of some of the hydrocarbon content without cracking the other hydrocarbons present, e.g. lowering pour point; Selective hydrocracking of normal paraffins (C10G32/00 takes precedence; improving or increasing the octane number or aromatic content of naphtha C10G35/00) > characterised by the catalyst used

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1980.
