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 words classes of and/or classes:
“Genocide begins, however improbably, in the conviction that classes of biological distinction indisputably sanction social and political discrimination.”
—Andrea Dworkin (b. 1946)
“Is a man too strong and fierce for society, and by temper and position a bad citizen,—a morose ruffian, with a dash of the pirate in him;Mnature sends him a troop of pretty sons and daughters, who are getting along in the dame’s classes at the village school, and love and fear for them smooths his grim scowl to courtesy. Thus she contrives to intenerate the granite and the feldspar, takes the boar out and puts the lamb in, and keeps her balance true.”
—Ralph Waldo Emerson (1803–1882)
