Resumo

Os níveis crescentes de CO2 na atmosfera são apontados como um dos principais responsáveis pelo aumento do efeito estufa. Há várias opções para a redução destes níveis sendo a Captura e Armazenamento de Carbono (CAC) apontada como uma forma eficaz de diminuir a concentração deste gás. Neste trabalho apresentam-se a carbonatação indireta de basalto, bem como, um estudo da abundância e ocorrência desse mineral e sua proximidade com fontes emissoras de CO2. Após a análise do mapa construído do cruzamento de regiões brasileiras com alta emissão e regiões onde se encontram basalto, conclui-se que as regiões Sul e Sudeste possuem um grande potencial para armazenamento geológico por possuir fontes emissoras muito próximas à área de basalto. A reação de carbonatação mostra-se eficiente, evidenciada após as análises por Absorção atômica, apresentando uma alta taxa de conversão dos íons lixiviados em carbonatos. As análises pelas técnicas MEV e EDS indicam a formação de precipitados de calcita ferrosa ressaltando a eficiência da carbonatação indireta.

Abstract

The increasing levels of CO2 in the atmosphere are indicated as a major contributor to the enhanced greenhouse effect. There are several options to reduce these levels and the Carbon Capture and Storage (CCS) is identified as an effective way to decrease the concentration of this gas. In this work, it is present the indirect carbonation of basalt, as well as, a study of abundance and occurrence of this mineral and its proximity to emission sources of CO2. After examining the map constructed by matching Brazilian regions with high emission and regions where there are basalt occurrences, one can conclude that the South and Southeast regions have a great potential for geological storage into basalt. This is due to the occurrence of emission sources very close to the basalt area. The carbonation reaction is efficient, as evidenced by atomic absorption analysis, showing a high rate of conversion of leached ions into carbonate. SEM and EDS analysis indicate the formation of precipitated ferrous calcite, which suggests an efficient indirect carbonation.
