SOME ASPECTS OF OXYCRACKING CATALYSTS REGENERATION
K.Y.Ajamov, E.А.Huseynova, L.А.Mursalova, S.R.Safarova

On the basis of the results of derivatographic studies of catalyst samples for oxycracking of vacuum gas oil, it is  establi shel that the surface of the spent catalyst is covered with 2 types of seal products: oxygen-containing organic oxidative seal products (OSP) and more stable oxygen-free high-molecular seal products (SP) having characteristic temperature anomalies. A staged mechanism of surface products decomposition has been proposed. The Kissenger method is used to estimate the activation energy for the destruction of surface seal products. It is noted that an increase in the duration  stay in the conditions of regeneration leads to a decrease in the activation energy
