Nowadays, the quality of fuels, in relation to the sulfur content, is carried out through the process of hydrodesulfurization. This work studies the synthesis and characterization of aluminophosphate (AlPO) impregnate with zinc (ZnPO), molybdenum (MoPO) or both (ZnMoPO), and its application in the sulfur removal from the gasoline through the adsorption process. The adsorbents were characterized by differential thermal analysis, x-ray fluorescence, x-ray diffraction, scanning electron microscopy and the specific area, volume and pore diameter. The adsorption tests run at 30°C under agitation at 150 rpm for 24 hours and the sulfur mensured by elemental analysis. The highest percentage of removal was 49% for MoZnPo, showing that the adsorbent presents promising for the sulfur adsorption process.
