Hydrogen production A distinction is made between "thermal partial oxidation" (TPOX) and "catalytic partial oxidation" (CPOX). The chemical reaction takes the general form: Idealized examples for heating oil and coal, assuming compositions CH and CH respectively, are as follows: The Kværner-process or Kvaerner carbon black & hydrogen process (CB&H) is a plasma reforming method, developed in the 1980s by a Norwegian company of the same name, for the production of hydrogen and carbon black from liquid hydrocarbons (CH). Of the available energy of the feed, approximately 48% is contained in the hydrogen, 40% is contained in activated carbon and 10% in superheated
Interstitial compound Interstitial compound An interstitial compound, or interstitial alloy, is a compound that is formed when an atom with a small enough radius sits in an interstitial “hole” in a metal lattice. Examples of small atoms are hydrogen, boron, carbon and nitrogen. The compounds are important industrially and include some transition-metal carbides and nitrides. The idea of interstitial compounds was started in the late 1930s and they are often called Hagg phases after Hägg. Transition metals generally crystallise in either the hexagonal close packed or face centered cubic structures, both of which can be considered to be made up of layers
