Resumen
This study performed the characterization of the commercial bentonite organoclay named Spectrogel C, showing to its affinity with some petroleum products. The surface area and pore size distribution were measured by the BET method, and presented a low area of 2.7 m3/g. The thermal stability was analyzed by the techniques of TG, DTG and DSC, which revealed a low moisture level and high content of organic salt, representing 25% of its total mass. The results of EDX showed that the clay is composed of aluminum silicates, Cl, Fe, Na and Mg. The texture was evaluated by SEM showed an irregular surface and defined particle size. XRD analysis proved that the clay belongs to smectite group is composed mainly of montmorillonite. The hydration and expansion tests showed good affinity with the organic complex and low affinity for the pure compounds. The Spectrogel organoclay presented potential to act in the removal of hydrocarbons. © (2014) Trans Tech Publications, Switzerland. 798-799
