dc.description.abstractEn este estudio, se sintetizaron aluminosilicatos de finos de cantera (residuos mineros), los cuales fueron utilizados para la adsorción y remoción de asfáltenos. La conversión del residuo se realizó mediante hidrólisis alcalina hidrotérmica, para la producción del silicato donor. Posteriormente se hizo una síntesis de los precipitados de aluminosilicatos amorfos mediante copolimerización con microondas. Estos fueron caracterizados antes y después por técnicas como Difracción de Rayos X, Fluorescencia de Rayos X e Infrarrojo. Los asfáltenos fueron obtenidos de crudos pesados-colombianos mediante el método de precipitación IP 43. Una vez obtenidos, se procedió a construir las isotermas de adsorción, para ello. Una vez ajustados los puntos experimentales se ajustaron al modelo de Langmuir.
dc.description.abstractAluminosilicates from quarry fines (mining waste) were synthesized, used for the adsorption and removal of asphaltenes. The residue conversion carries t by hydrothermal alkaline hydrolysis to produce the donor silicate. Subsequently, a synthesis of the amorphous aluminosilicate precipitates heat by microwave copolymerization. These characterize before and after by techniques such as X-ray Diffraction, X-ray Fluorescence, and Infrared. The asphaltenes were obtained from heavy Colombian crude oils employing the IP 43 precipitation method. It gets that the solids adsorbed and conformed to the Langmuir model.
