This generally requires an iron catalyst and pressures above 200 atmospheres.
The KAAP version of this reaction uses a ruthenium catalyst to allow for lower pressure, and Gerhard Ertl received the 2007 Nobel Prize in part for determining its molecular mechanism. An early stage of this reaction needs a methanator to prevent the build up of carbon monoxide, and its namesake first investigated this process because of the scarcity of Chilean saltpeter. This generally requires an iron catalyst and pressures above 200 atmospheres. Syngas provides one of the reactants for this process, which in turn provides the synthetic fertilizer that grows food for about half of the world's population. Name this chemical process in which nitrogen and hydrogen gases are combined to make ammonia.
