Separation of hydrogen or hydrogen-containing gases from gaseous mixtures, e.g. purification

Introduced: January 1980

Title

Titles differ between systems:

IPC: Separation of hydrogen or hydrogen containing gases from gaseous mixtures, e.g. purification

CPC: Separation of hydrogen or hydrogen-containing gases from gaseous mixtures, e.g. purification

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 > Separation of hydrogen or hydrogen containing gases from gaseous mixtures, e.g. purification

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) > Separation of hydrogen or hydrogen-containing gases from gaseous mixtures, e.g. purification

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.
