| Abstract |
|
Nine gas-phase reactions that can be accomplished with an inexpensive, commercially-available glass-encased, heterogeneous palladium catalyst tube are described. The catalyzed reactions are suitable for demonstrating gas-phase reactions in the classroom or teaching laboratory. The reactions described include air or oxygen oxidations (CH4 + O2, CO + O2, NH3 + O2), hydrogenation of ethene, thermal decomposition of nitrous oxide, oxidations involving nitrogen dioxide (CH4 + NO2, CO + NO2), and two oxidation reactions involving nitrous oxide (N2O + NH3, N2O + CO). Several of the reactions demonstrate processes that take place in an automotive catalytic converter. In all cases, the products can be tested by simple chemical methods.

Information for the construction of the catalyst
tube device from a used automobile
catalyst with photographs of an automotive catalyst cut in half and segmented
is available.
