The role of zeolite pore structure during deactivation by coking

Abstract
Residues accumulating within the cavities of a small‐pore zeolite, isolated by extraction, are composed of a series of aromatics up to a distinct cutoff at pyrene. Similar analysis of partiall‐regenerated catalyst reveal pathways by which residue oxidation can occur and pathways by which these residues can participate during methanol decomposition.
