Abstract :
Synthesis of zeolite 13X from modified natural Iranian kaolin at 65˚C for 72 h at various concentration of NaOH solution was investigated. Metakaolinization process was done at 900˚C for 2 h. NaOH solution with different concentrations, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4 M were separately mixed with metakaolins. A mixture of zeolite 13X, A, quartz and hydroxysodalite (HS) was obtained. The products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The prepared zeolite 13X has been used to study the adsorption of carbon dioxide, and the results are compared with commercial zeolite 13X.

سنتز زئوليت 13X از كائولين طبيعي ايراني در دماي 65 درجه سانتي گراد به مدت 72 ساعت در غلظت هاي مختلف محلول سود مورد بررسي قرار گرفت. فرآيند متاكائوليزاسيون در دماي 900 درجه سانتي گراد به مدت 2 ساعت انجام شد. محلول سود با غلظت هاي 1، 5, 1، 2، 2٫5، 3، 3٫5 و 4 مولار با متاكائولين
مخلوط شد. مخلوطي از زئوليت 13X و كواتز و هيدروكسي سوداليت بدست آمد. مشخصات محصول با آزمايش هايXRD, FT-IR و SEM مورد بررسي قرار گرفت. محصول توليد شده براي جذب دي اكسيد كربن مورد استفاده قرار گرفت و نتايج با زئوليت طبيعي مقايسه شد.
