Process for the preparation of carbon monoxide and/or .

Jan 23, 1996 · The present invention provides a process for the preparation of carbon monoxide and/or hydrogen from a hydrocarbon feedstock. The hydrocarbon feedstock is subjected in a first stage to a catalytic partial oxidation process in which it is contacted, as a gaseous mixture comprising the hydrocarbon feedstock and an oxygen-containing gas, which gaseous mixture also comprises nitrogen.

Carbon - Wikipedia

Carbon - Wikipedia

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.
