Abstract

Beneficiation through gasification of coal combustion ash coming from an industrial power plant aimed at its reuse as adsorbent is dealt with. The raw ash was gasified in a tubular reactor at 850°C for times ranging from 10 to 60 min, using either steam or CO2 as gasifying agents. The relationships among ash properties, gasification treatments and properties of the gasified ashes deserve investigation. Therefore, ash characteristics (such as carbon content, porosimetric, diffractometric and granulometric properties) were correspondingly determined. In the light of a critical analysis of the obtained results, gasification conditions able to make the parent ash a potentially better adsorbent material were defined, with a particular emphasis on similarities and differences between steam and CO2 gasification.
