Popis:	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 remaining in the cages or the channels of zeolites after dealumination. AI-N.M.R. shows that extra-framework but also framework aluminum can be involved in the process of coking.
