The Kværner-process or Kvaerner carbon black & hydrogen process (CB&H)[1] is a method, developed in the 1980s by Aker Solutions of Norway, for the production of hydrogen from hydrocarbons (CnHm), such as methane, natural gas and biogas.

[edit] Description

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 \rightarrow n C + \frac{m}{2} H_2}

The biggest advantage over all other known reformation methods (steam reforming, partial oxidation, etc.) is that the natural gas is transformed 100% into pure carbon and hydrogen in an energy-efficient way. 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.

[edit] Plasma variation

A variation of this process using plasma arc waste disposal was presented in 2009. Methane and natural gas is converted to hydrogen, heat and carbon using a plasma converter.[2]
