The Kværner process or the Kværner carbon black and hydrogen process (CB&H) is a method of producing carbon black and hydrogen gas from hydrocarbons such as methane, natural gas and biogas. The process was developed in the 1980s by the Norwegian engineering firm Kværner, and was first commercially exploited in 1999.
In comparison to other reformation methods such as steam reforming and partial oxidation the natural gas is efficiently and completely transformed into pure carbon and hydrogen. 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.
