Production of hydrogen; Production of gaseous mixtures containing hydrogen

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Hydrogen; Gaseous mixtures containing hydrogen; Separation of hydrogen from mixtures containing it; Purification of hydrogen; Reversible storage of hydrogen > Production of hydrogen; Production of gaseous mixtures containing hydrogen

CPC:

Hydrogen; Gaseous mixtures containing hydrogen; Separation of hydrogen from mixtures containing it; Purification of hydrogen; Reversible storage of hydrogen (production of water-gas or synthesis gas from solid carbonaceous material C10J) > Production of hydrogen; Production of gaseous mixtures containing hydrogen

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
