Hydrogen production because it is more efficient than separate hydrogen, steam and power plants. Air Products recently built an integrated steam reforming / co-generation plant in Port Arthur, Texas. Hydrogen production from natural gas or other hydrocarbons is achieved by partial oxidation. A fuel-air or fuel-oxygen mixture is partially combusted resulting in a hydrogen rich syngas. Hydrogen and carbon monoxide are obtained via the water-gas shift reaction. Carbon dioxide can be co-fed to lower the hydrogen to carbon monoxide ratio. The partial oxidation reaction occurs when a substoichiometric fuel-air mixture or fuel-oxygen is partially combusted in a reformer or partial oxidation reactor.
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
