Classes of Heterogeneous Catalysts
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:
“The most powerful lessons about ethics and morality do not come from school discussions or classes in character building. They come from family life where people treat one another with respect, consideration, and love.”
—Neil Kurshan (20th century)
