WebLangmuir-Hinshelwood with no dissociation of hydrogen where LA, BL and H 2 are adsorbed on different sites (NCLH1.2) and non-competitive Langmuir-Hinshelwood with dissociation of hydrogen where LA, BL (butyl levulinate) and H 2 are adsorbed on different sites (NCLH2.2) are the best model to describe this system. WebMay 31, 2024 · The Langmuir-Hinshelwood-Hougen-Watson (LHHW) The Eley–Rideal mechanism describes a reaction between a reactant which has chemisorbed and another one which has not chemisorbed . The defining characteristic of an Eley–Rideal reaction is that one of the reactants is not chemisorbed locally, and hence, not in equilibrium with …
WebThe following reactions follow a Langmuir-Hinshelwood mechanism [1]: 2 CO + O 2 → 2 CO 2 on a platinum catalyst. CO + 2H 2 → CH 3 OH on a ZnO catalyst. C 2 H 4 + H 2 → C 2 H 6 on a copper catalyst. N 2 O + H 2 → N 2 + H 2 O on a platinum catalyst. C 2 H 4 + ½ O 2 → CH 3 CHO on a palladium catalyst.
