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.<eng> vorgelegt von Riaz Muhammad GutachterInnen: Axel Schulz (Universität Rostock, Institut für Chemie) ; Hendrik Kosslick (Universität Rostock, LIKAT) ; Christian Jäger (BAM Berlin) ; Raja Al Otaibi (KACST, Saudi Arabia) Dissertation Universität Rostock 2018 540 541 540 35.17 35.49 http://purl.uni-rostock.de/rosdok/id00002519 https://doi.org/10.18453/rosdok_id00002519 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002519-8 https://d-nb.info/1293657506/34 Green natural zeolite catalyst-preparation, characterization and acid catalytic performance--(DE-627)102921820X urn:nbn:de:gbv:28-rosdok_id00002519-8 doi: 10.18453/rosdok_id00002519 oclc: 1135657917 ppn: (DE-627)1671440013
