Comparación del potencial oxidativo de Acidithiobacillus ferrooxidans, en un proceso de biodesulfurización de carbón

Abstract: <p>En este estudio se comparó la actividad oxidativa de dos cepas de Acidithiobacillus ferrooxidans en un proceso de desulfurización, empleando un carbón sub-bituminoso alto en azufre (2.30% de azufre total, con 1.06% pirítico, 1.10% orgánico y 0.14% de sulfatos), proveniente de la mina “La Guacamaya” ubicada en Puerto Libertador–Córdoba, Colombia. Se realizaron ensayos a nivel de erlenmeyer, la concentración de hierro total en la solución fue de 200 mg/L y 1200 mg/L respectivamente, empleando sulfato fe… Show more

“…Coals from El Cerrejón are typically bituminous with a volatile content of 37.4% and an ash content of 6.8% (dry basis) (Feng et al, 2003). Coals from Guacamaya are sub-bituminous with a high S content (2.30% total S with 1.06% as pyritic, 1.10% as organic and 0.14% from sulfates) and high volatile content (Prada et al, 2016). While detailed chemical characterizations of El Cerrejón coal have been reported elsewhere (Nathan et al, 1999), other Colombian coals, such as those obtained from the Guacamaya mine, have not been sufficiently characterized.…”
