Resumen en español
El incremento de las emisiones de gases de efecto invernadero (principalmente CO_2) al ambiente lleva al agravamiento del calentamiento global, lo cual es un problema de gran interés en la actualidad. El consumo de energía va en aumento, y entre las plantas de generación eléctrica, las que utilizan combustibles fósiles son las que emiten mayores cantidades de CO_2. Dentro de las opciones que se están investigando para lograr los objetivos de reducción de CO_2 a mediano y largo plazo, la captura de CO_2 post combustión en centrales térmicas es un método promisorio. A su vez, existen una serie de tecnologías, aún en las primeras etapas de desarrollo, entre las que destaca la absorción de CO_2 empleando materiales cerámicos. En este trabajo se desarrolló un material cerámico para captura de CO_2 a altas temperaturas y bajas presiones parciales: el ortosilicato de litio (Li_4SiO_4). Se sintetizó de manera exitosa el Li_4SiO_4, tanto por la vía convencional, como por vía húmeda, y también empleando agentes dopantes. Se evaluaron sus propiedades y se comprobó su estabilidad y capacidad de regeneración luego de 5 ciclos de uso.
Resumen en inglés
The increase of the greenhouse gas emissions (mainly CO_2) in the environment leads to global warming, which is a problem of great interest today. Energy consumption is increasing, and among electricity generation plants, those that use fossil fuels are the ones that emit the greatest amounts of CO_2. Among the options being investigated to achieve the CO_2 reduction objectives in the medium and long term, post-combustion CO_2 capture in thermal power plants is a promising method. At the same time, there are a series of technologies, still in the early stages of development, among which the absorption of CO_2 using ceramic materials stands out. In this work, a ceramic material was developed to capture CO_2 at high temperatures and low partial pressures: lithium orthosilicate (Li_4SiO_4). Li_4SiO_4 was successfully synthesized, both by the conventional and wet methods, and also employing doping agents. Its properties were evaluated and its stability and regeneration capacity were verified up to 5 cycles of use.
