Uso de carvão ativado na remoção de CO2

Abstract: No presente trabalho, foram estudadas as isotermas de adsorção do CO2 sobre carvão ativado produzido a partir de endocarpo de coco (Cocos nucifera L.) que constitui um resíduo gerado em diversos processos agroindustriais. O carvão sintetizado foi caracterizado por espectroscopia de infravermelho com transformada de Fourier (FTIR), fluorescência de raios X (FRX) e quantificação de grupos ácidos e básicos via método de Boehm. Na obtenção das isotermas de adsorção do CO2 foi utilizada a técnica volumétrica estáti… Show more

“…The initial pressure dropped as a consequence of the adsorption of CO 2 at the adsorbent surface until equilibrium was reached. This method determined the amount of CO 2 adsorbed by indirect measurement of the initial pressure of the system since the volume of the column and the volume occupied by the adsorbent are known [14]. To do so, it was necessary to determine the volume occupied by free CO 2 inside the column, according to:…”
