Carbonaceous particles in coal combustion stack ash and their interaction with polycyclic aromatic hydrocarbons

Conference ·
OSTI ID:5589535

Carbonaceous particles consisting of uncombusted coal, coal coke, and intermediates are concentrated in the large particle size fractions (> 14 ..mu..m) of stack ash. Although they do not constitute a major portion of the ash, they appear to contribute significantly to the interaction of fly ash with organic matter. The carbonaceous particle-enriched fractions are more sorptive, have higher levels of organic matter, and exhibit higher specific surface areas than mineral or magnetic particle-enriched subfractions. Extraction recoveries of organics from fly ash appear to be limited mainly by the carbonaceous particles.
