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
Law of definite proportions Law of definite proportions In chemistry, the law of definite proportion, sometimes called Proust's law or the law of definite composition, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation. For example oxygen makes up about / of the mass of any sample of pure water, while hydrogen makes up the remaining / of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry. The law of constant
