Реферат:
The hydrothermal stability of hydroxyl groups in the HY-HZSM-5 system (stabilized and unstabilized) was investigated. HNaY and HNaZSM-5 zeolites had greater hydrothermal stability in mixtures than in unmixed forms. Mixtures simultaneously stabilized were as good as USY alone; no dehydroxylation was detected during water vapour interaction. NMR MAS measurements indicated the presence of extralattice aluminium phases. The influence of unextracted extralattice aluminium phases during simultaneous stabilization or activation by dehydroxylation is possible. Acid Bronsted centre concentrations and specific surface area were measured. Zeolite structure was preserved after mixing by milling or water vapour interaction.
