Abstract

Zeolitler,
simektit grubunun mikro gözenekli üyeleridir ve endüstriyel uygulamalarda geniş
kullanım alanı bulurlar. Zeolitlerin yüzey, morfolojik, mineralojik ve
fizikokimyasal özellikleri farklı aletli analiz teknikleri ile incelenmiştir.
Yüzey fonksiyonel grupları Fourier dönüşümlü kızılötesi (FTIR) spektrumları ile
belirlenmiştir. Malzemelerin morfolojisi ve yüzey fonksiyonel grupları taramalı
elektron mikroskobu (SEM) görüntüleri ve X ışını kırınım desenleri yardımıyla
analiz edilmiştir. Zeolitin, Brunauer-Emmett-Teller (BET) yüzey alanı, gözenek
hacmi, gözenek büyüklüğü dağılımı ve ortalama gözenek çapı da dâhil gözenek
özellikleri, -196 ^○C de N₂
atmosferinde fiziksel adsorpsiyon ile belirlenmiştir. Zeolit yüzeyini
karakterize etmek için ters gaz kromatografisi (TGK) uygulanmıştır.

Inverse Gas Chromatographic Determination of the Surface Properties of ZSM-5 Zeolite

Abstract

Zeolites are microporous
members of the smectite group and are widely used in industrial applications.
The surface, morphological mineralogical and physico-chemical properties of
zeolites are studied by different instrumental analysis techniques.
The surface
functional groups were determined by Fourier transform infrared (FTIR) spectra.
The morphology and surface
functional groups of the materials have been analyzed with the aid of scanning
electron microscopy (SEM) images and X-ray diffraction (XRD). The pore
properties including the Brunauer-Emmett-Teller (BET) surface area, pore volume, pore size distribution and average pore diameter
of the zeolite was determined by physical adsorption of N₂ at -196 ^○C. Inverse gas
chromatography (IGC) was applied to characterize the surface of zeolite.
