Reforming 1
Reforming 1 :
A general name for the reaction of a hydrocarbon, such as methane, with water and/or carbon dioxide, to produce a mixture of carbon monoxide and hydrogen. If water is used, it is called steam reforming or steam cracking. The reactions are endothermic and require a catalyst: CH4 + H2O + CO + 3H2. The usual catalyst is nickel on an oxide support. A second reaction also takes place, the shift reaction, also known as the water gas shift reaction: CO + H2O + CO2 + H2. The shift reaction can be conducted in a second reactor, catalyzed by a mixture of iron and chromium oxides. The product of reforming is known as synthesis gas, or syngas, and is mostly used in the manufacture of ammonia and methanol. One of the earliest steam reforming processes was developed in Germany by I.G. Farbenindustrie in 1926. See also: catalytic reforming. (Check source for accuracy of chemical formula)
