DIFF Subgroup
C10G 47/02 characterised by the catalyst used
Introduced: January 1980
Full Title
Full titles differ between systems:
IPC:
Cracking of hydrocarbon oils, in the presence of hydrogen or hydrogen-generating compounds, to obtain lower boiling fractions > characterised by the catalyst used
CPC:
Cracking of hydrocarbon oils, in the presence of hydrogen or hydrogen- generating compounds, to obtain lower boiling fractions (C10G15/00 takes precedence; destructive hydrogenation of non-melting solid carbonaceous or similar materials C10G1/06) > characterised by the catalyst used
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
IPC defines codes here since 1980.
