The catalytic potential of sludge based materials produced by steam or CO2 activation
from non treated dewatered raw sludge or dewatered mesophilic anaerobically digested sludge
were tested in the oxidation of phenol. Batch and continuous experiments were conducted to
assess activity and stability of carbons in terms of phenol conversion, carbon burn off and metal
leaching. Overall, catalytic activity of materials can be considered very satisfactory when
compared to commercial carbons. However, further research on preparation is required to
improve their thermal and mechanical stability and resistance to metal leaching.Peer ReviewedPostprint (published version
