Abstract
The adsorption of propene and its conversion into coke on a FCC cataly st was studied as a function of the temperature and of the residual ac tivity after selective poisoning of the acid sites. it is shown that c oke formation involves the strongest acid sites, capable of retaining 2,6-dimethylpyridine at 450-degrees-C. The nature of the coke and its reactivity were found to change with the deposition temperature. The c oke obtained in the temperature range 300-degrees-C - 500-degrees-C co uld be resolved by DSC into a mixture of two components of different r eactivity.
