The effect of pre-oxidation on the porosity evolution in heavy-oil fly ash subjected to activation with CO2 has been investigated. After preliminary acid leaching, used to reduce the mineral matter content, the leached fly ash has been oxidised in air at 250 °C for 36 h

Abstract
The effect of pre-oxidation on the porosity evolution in heavy-oil fly ash subjected to activation with CO2 has been investigated. After preliminary acid leaching, used to reduce the mineral matter content, the leached fly ash has been oxidised in air at 250 °C for 36 hFile in questo prodotto:
