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 > Separation of hydrogen or hydrogen containing gases from gaseous mixtures, e.g. purification > by contacting with solids; Regeneration of used solids

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 > by contacting with solids; Regeneration of used solids

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 1980.
