Diferencias entre el uso de sulfato férrico y cloruro férrico en la biodesulfurización de un carbón con tamaño de partícula grueso

Abstract: <p>Se evaluaron tres fuentes de hierro (FeSO4, Fe2(SO4)3 y FeCl3) a diferentes concentraciones (150, 700 y 1250 mg Fe/L) en procesos de biodesulfurización de un carbón con tamaño de partícula grueso, utilizando un consorcio de Acidithiobacillus ferrooxidans (ATCC 23270) and Acidithiobacillus thiooxidans (ATCC 15494). Al usar 150 mg Fe2+/L (FeSO4), luego de 12 días se obtuvo 31.14% de pirita oxidada. Al reemplazar FeSO4 por Fe2(SO4)3, la oxidación mejoró en un 21.16%. Aunque los ensayos con las mayores co… Show more

“…Currently, available inorganic coagulants can be divided into two groups: coagulants based on aluminium (e.g., aluminium sulphate and aluminium poly chloride) and iron (e.g., ferric sulphate and ferric chloride) (Aziz et al 2017;Caicedo-Pineda and Márquez-Godoy 2016). Most coagulant producers use industrial-grade aluminium and iron ores as raw materials.…”
