SUMMARY:

The more than 255 zeolite structures know today,ony ten (10) are produced industrially. This is because many of the syntheses are not optimized or are too expensive to scale. To enable more structures to be produced industrially synthesis costs can be reduced by replacing tradicional raw materials with alternative sources of Si and Al. Among the alternative sources of Si na Al, natural materials such as clay minerals, industrial waste can be used, between others. We are proposing in this work the use of fragmented materials displaced by the drill to the surface, residue from drilling oil wells called gutter sample. The zeolite to be obtained using this residue will initially be LTA zeolite. The materials obtained materials, as well as the starting ones, were characterized by X-ray difraction, X- ray fluorescence, scanning electron microscopy and Co2 adsorption. As a result, it was possible to observe the formation of zeolite materials through the identification of characteristic Bragg reflections and characteristics cubic morphology of zeolite LTA. The Si/Al ratio of the samples was close to Unity, as expected for this topology. Once the fearsibility of zeolite synthesis using this residue has been proven, it is intended to expand its use to another zeolite structure.
