摘要：

The adsorption of propene and its conversion into coke on a FCC catalyst was studied as a function of the temperature and of the residual activity after selective poisoning of the acid sites. it is shown that coke 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 coke obtained in the temperature range 300-degrees-C - 500-degrees-C could be resolved by DSC into a mixture of two components of different reactivity.
