Rare earth metals and their intermetallics have found applications in heterogeneous catalysis, including cracking, hydrogenation, and other reactions of hydrocarbons, yet little has been published on chemisorption of hydrocarbons by rare earths. In the present communication the authors report on exploratory calorimetric experiments with the adsorption of initial doses of C{sub 3}H{sub 6}, C{sub 2}H{sub 2}, and CH{sub 4} admitted to polycrystalline dysprosium films at room temperature. The obtained data are interpreted in terms of thermochemical cycles utilizing data of their previous thermochemical and XPS measurements of the interaction of hydrogen, carbon monoxide, and oxygen with films of rare earths.
