Torrefaction subsequent to pelletization: Characterization and analysis of furfural residue and sawdust pellets.

Torrefaction integrated with pelletization has gained increasingly interest as it enhances the characteristics of fuel pellets (e.g. hydrophobicity and energy density).

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.

Microwave-assisted pyrolysis of textile dyeing sludge, and migration and distribution of heavy metals.

This study investigated the pyrolysis characteristic of textile dyeing sludge (DS) using an auger pyrolyser under microwave irradiation at different pyrolysis temperature. The migration and distribution characteristic of heavy metals and their potential ecological risks were investigated using inductively coupled plasma mass spectrometry (ICP-MS) techniques. Temperature and additives (e.

Microwave pyrolysis of textile dyeing sludge in a continuously operated auger reactor: Condensates and non-condensable gases.

This paper investigated an auger pyrolyser under microwave irradiation using textile dyeing sludge (DS) as the feedstock. Microwave power, temperature, auger speed, gas velocity and addition of catalysts were studied. In terms of ICP-MS, Cu and As concentrations in condensates, depending on pyrolysis temperatures, exceeded the wastewater discharge standard in China.

Microwave pyrolysis of textile dyeing sludge in a continuously operated auger reactor: Char characterization and analysis.

Textile dyeing sludge (DS) contains toxic organic and inorganic substances, and needs to be disposed by appropriate technologies. This paper investigated an auger pyrolyser under microwave irradiation for treatment and disposal of DS. Microwave power, temperature, gas and solid residence times, addition of catalysts were studied.
