Abstract

Thermogravimetry is used for regeneration of the alumina catalyst which was deactivated by coke, formed in the transformation of 1,3-butadiene in a fixed bed continuous flow reactor. The Vyazovkin model-free kinetic analysis has been applied to data on thermal oxidation of carbonaceous deposits on the catalyst. This analysis has allowed us to estimate the activation energy (E) as a function of α (conversion) and to predict the time required to remove coke at a given temperature.
