摘要：
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 decoking. We also showed that complete reoxidation under relatively mild conditions did not permit to restore the initial catalyst.
