Pyrolysis of textile dyeing sludge in fluidized bed and microwave-assisted auger reactor: Comparison and characterization of pyrolysis products.

This paper investigated fluidized bed pyrolysis (FBP) and microwave-assisted auger pyrolysis (MWAP) for treatment and disposal of textile dyeing sludge (DS), and the products were analyzed and compared. MWAP achieved higher yields of char and condensate, and lower non-condensable gas yields compared to FBP. The yields of CO from FBP were much higher than those from MWAP at 450-850 °C.
