C01B 3/323

Catalytic reaction of gaseous or liquid organic compounds other than hydrocarbons with gasifying agents

Introduced: January 2026

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 > by reaction of gaseous or liquid organic compounds with gasifying agents, e.g. water, carbon dioxide or air > Catalytic reaction of gaseous or liquid organic compounds other than hydrocarbons with gasifying agents

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 > by reaction of gaseous or liquid organic compounds with gasifying agents, e.g. water, carbon dioxide or air > Catalytic reaction of gaseous or liquid organic compounds other than hydrocarbons with gasifying agents

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

IPC defines codes here since 2026.
