Kværner-process

The Kværner-process or Kvaerner carbon black & hydrogen process (CB&H) [ [http://www.interstatetraveler.us/Reference-Bibliography/Bellona-HydrogenReport.html Bellona-HydrogenReport] ] is a method, developed in the 1980s by a Norwegian company of the same name, for the production of hydrogen from hydrocarbons (C_nH_m), such as methane, natural gas and biogas.

Description of the Process

The hydrocarbons are separated into their components, carbon and hydrogen in a plasma burner (see Plasma, Electric arc) at around 1600 C.

Reaction: $mathrm\{C\_n\; H\_m\; +\; Energy\; ightarrow\; n\; C\; +\; frac\{m\}\{2\}\; H\_2\}$

The biggest advantage over all other known reformation methods (steam reforming, partial oxidation etc) is that the carbon is converted to carbon dioxide. Of the available energy of the feed, approximately 48% is contained in the Hydrogen, 40% is contained in activated carbon and 10% in superheated steam.

Production

The Kværner-process is used for the production of hydrogen at the Hynor hydrogen station in Bergen.
