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 diselenide Carbon diselenide Carbon diselenide is an inorganic compound with the chemical formula CSe. It is a yellow-orange oily liquid with pungent odor. It is an analogue of carbon disulfide (CS). This light-sensitive compound is insoluble in water and soluble in organic solvents. Carbon diselenide is a linear molecule with D symmetry. It is produced by reacting selenium powder with dichloromethane vapor near 550 °C. It was first reported by Grimm and Metzger, who prepared it by treating hydrogen selenide with carbon tetrachloride in a hot tube. Like carbon disulfide, carbon diselenide polymerizes under high pressure. The structure of the polymer
