Abstract

Three variants of solid-state ion exchange were studied. Iron exchange was found to proceed in the first case, in the FeCl2+NH4ZSM-5→ FeZSM-5 + NH4Cl↑ process, even at low exchange capacity (Si/Al = 25). The second, Fe2O3 (hematite) + HZ direct reaction does not result in any noticeable interaction for either Z = Y or ZSM-5. This process can significantly be promoted by introducing CCl4 vapor via forming chlorine-containing mobile species. However, the structure of the Y zeolite largely collapses during this treatment, whereas the crystalline state of ZSM-5 is preserved.
