Messerschmidtt process

Industrial production. Hydrogen can be produced commercially by several processes. Historically, it was first produced from coke oven gas, and in Germany by the Fischer-Tropsch process and to a lesser extent by the Messerschmidtt process. The hydrogen was separated from the coke oven gas (i.e., 56 vol.% H, 26 vol.% CH, 7 vol.% CO and others) by liquefaction and used afterwards in ammonia synthesis. The Fischer-Tropsch process... 

Carbon monoxide was later removed from the water gas either by hquefaction or by conversion into carbon dioxide and absorption by sodium carbonate. On the other hand, the Messerschmidtt process and later the Lanes process" also called the steam-iron process consisted of decomposing water vapor (steam) passing it over a fixed bed containing turnings of iron or prereduced iron oxides at red heat (600-650 C) according to the following chemical reaction ...
