oksidointireformointi
Oksidointireformointi, commonly known in English as steam reforming, is a crucial industrial process used to produce hydrogen and synthesis gas. It involves reacting a hydrocarbon feedstock, typically natural gas (methane), with steam at high temperatures and pressures in the presence of a catalyst. The primary reaction can be represented as CH4 + H2O <=> CO + 3H2. This reaction is endothermic, meaning it requires heat to proceed. A secondary, highly exothermic reaction, the water-gas shift reaction, is often coupled with steam reforming to maximize hydrogen production and adjust the carbon monoxide to hydrogen ratio: CO + H2O <=> CO2 + H2.
Common catalysts used in steam reforming are based on nickel, supported on materials like alumina. The process
Oksidointireformointi is a cornerstone of the chemical industry, providing the hydrogen necessary for ammonia production (for
