Although the majority of heterogeneous catalysts are solids, many variations exist.
Reacting phases | Examples | Comment |
---|---|---|
solid + gas | Ammonia synthesis from N2 + H2 over iron catalysts | |
solid + solution | hydrogenation of fatty acids with nickel | used for the production of margarine |
immiscible liquid phases | hydroformylation of propene | catalyst in aqueous phase, reactants and products mainly in nonaqueous phase |

Famous quotes containing the word classes:
“There are four classes of idols which beset mens minds. To these for distinctions sake I have assigned namescalling the first class Idols of the Tribe; the second, Idols of the Cave; the third, Idols of the Market-Place; the fourth, Idols of the Theatre.”
