| abstract: |
|
Natural clinoptilolite zeolite-CLIN was acidified by ammonium ion exchange followed
by calcination and HCl treatment under soft conditions. The influence of the modification
type and treatment conditions on the structure, morphology and acidity was studied
by XRD, SEM, FTIR, ICP-AES, TG/DSC, ammonia-TPD, 1H, 27Al and 29SI MAS NMR and N2-ads-des.
High temperature calcination of NH4-CLIN and concentrated acid has a more severe impact
on the clinoptilolite structure. H-CLIN catalysts are potential and active acid catalysts
and synthesis-structure-porosity-acidity-activity relationship was found.
