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
Carbon–hydrogen bond activation substitution at the carbon also greatly affects selectivity; the secondary methylene position is preferred over the terminal methylene position because the former has a secondary carbon while the latter has a primary one. In the oxidation of cyclohexane compound, the tertiary site on the ring is preferential over the tertiary site of the isopropyl substituent. The two methyl groups hinder the oxidation on the isopropyl group, making the less hindered cyclohexyl site more favorable. In contrast to innate selectivity, guided selectivity results from external reagents or directing groups affecting the nature of specific C-H bonds. The figure above demonstrates the
