C01B 3/34

by reaction of hydrocarbons with gasifying agents

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

Of 6 combined children, 4 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1980.
