Abstract  

The aim of this work is the synthesis and the characterization of a microporous material obtained from gels with titanium and silicon: NTS (titanosilicate). The structure of NTS zeotype is similar to that of AM-1 and JDF-L1 (titanosilicates). The synthesis were carried out with gels of composition: 3.5Na2O–yTiO2–4.48HCl–xSiO2–110H2O with 1.0≤x≤12.0 and 0.2≤y≤0.7. The temperature of reaction was 1902C. In most of the cases NTS was prepared in a pelletted form. NTS pellets are produced at TiO2 content higher than 0.3 moles and SiO2 comprised between 3 and 7. NTS in a powder form is produced for TiO2<0.3 and SiO2 between 3 and 5 moles. It describes crystallization field and the kinetic curves of the titanosilicate. The samples are characterized by X-ray diffraction (XRD), thermogravimetry (TG), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), nuclear magnetic resonance spectroscopy-high resolution solid state MAS 29Si-NMR, scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) X-ray microanalysis.
