Self-sustained spontaneous and reproducible oscillations of 2-methylpropeneconversion have been observed experimentally under certain conditions. The temperature of the catalystbed well reflected the oscillatory course of 2-methylpropene conversion. The observed oscillations exhib-ited exceptionally long periods ranging from 11 to 22 h depending on the prevailing space velocity. Theappearance of oscillations of the conversion has been ascribed to the complex interaction between theexothermic reaction, heat transfer and a reversible decrease in the catalyst activity. Possible mechanismsof temporary catalyst activity decrease have been proposed.
