- Abstract
- Combined use of Xe-129 NMR and H-1-imaging NMR shows that coking of an HY zeolite pellet results in a heterogeneous distribution both at the nanometric and macroscopic scales. This distribution depends upon the direction of the now of reactant. It was also observed how diffusion of dimethylpentane occurs through both uncoked and coked sections of the pellet.
