摘要

Thermokinetic oscillations obtained during the heterogeneous catalytic oxidation of methanol on Pd/LiAl_5O_8 in a dynamic calorimeter were characterized by an overall activation energy. This parameter was determined using the minimum and maximum values of the temperature oscillations. Using bifurcation diagrams with oxygen or methanol as bifurcation parameters. E values for all heating loss laws were calculated which are within the range for heterogeneous catalytic oxidation reactions. The obtained results have been discussed.
