Resumo: In this work, the use of raw powder glass as a silica source was studied for silica MFI zeolite synthesis. The zeolite was successfully obtained by employing this silica source treated with a hydrochloric acid solution and as provided. Synthesis was performed using hydrofluoric acid as the mineralizing agent and tetrapropylammonium hydroxide as the organic structure-directing agent. Scanning electron microscopy micrographs revealed elongated crystals of larger size when the raw powder glass employed contained a lower silica percentage. X-ray diffraction patterns of the resulting products indicated that Fe-silicalite-1 was obtained and the Si/Fe ratio was calculated by interpolating the unit cell volume of the obtained zeolites in a linear regression created by employing literature data. The presence of iron was also confirmed by the presence of ν(Si–O–Fe)sym.str in the infrared spectra. Thermogravimetric analyses indicated good stability. This study concluded with a reproducible and optimized method for obtaining this versatile zeolite from raw powder glass with different compositions
