Abstract: | Résumé On présente les résultats obtenus dans l'évaluation des paramètres cinétiques de la réaction de décomposition thermique de l'anhydride chromique déposé sur de l'alumine. Grâce aux données sur l'influence de la teneur en anhydride chromique et de la vitesse de chauffage sur les paramètres cinétiques, on obtient des conclusions sur les conditions d'obtention du catalyseur Cr2O3/Al2O3.
Results obtained in the determination of the kinetic parameters of the thermal decomposition of CrO3 on alumina are presented. The experimental data on the effects of CrO3 concentration and heating rate on the kinetic parameters are used to draw conclusions on the conditions of preparation of Cr2O3/Al2O3 catalysts.
Zusammenfassung Die bei der Bestimmung der kinetischen Parameter der thermischen Zersetzungsreaktion von CrO3 auf Aluminiumoxid-Träger erhaltenen Ergebnisse werden erörtert. Aus den Versuchsangaben über den Einfluß der Cr2O3-Konzentration und die Aufheizgeschwindigkeit auf die kinetischen Parameter werden Schlüsse bezüglich der Herstellungsbedingungen der Cr2O3/Al2O3-Katalysatoren gezogen.
