NMR occupies an important place in the study of the deactivation of zeolites by coking. Indeed, association of the resonances of several nuclei has shown that it is possible to investigate: the nature of the carbonaceous deposits; under certain condi

The location of coke formed during conversion of methanol or acetone on HZSM-5 zeolites has been examined using 129-Xe NMR spectroscopy. The results show that the type of reaction and the method of regeneration have great importance for the location

Zeolites coking has been studied by129Xe-NMR technique. The distribution of the coke is heterogeneous on the supercage surface at low cokage level. When coking increases up to 10% the supercages are lined with coke and the residual internal volume co

Location of coke produced during cracking of hexane and ortho-xylene on HY zeolites has been studied by 129-Xe NMR. Coupled with HRADS (high resolution adsorption) technique we obtained information about the distribution of coke during coking and dec

Interactions of aluminum species in HY or HZSM5 zeolites and coke formed during cracking or conversion of organic molecules have been investigated by 129- Xe and 27-AI N.M.R. It is shown that Xe- N.M.R. is able to detect extra-framework aluminum rema
