AbstractThe high nitrogen content in wood waste containing urea formaldehyde from furniture industry hampers its utilization as a clean fuel. Herein, microwave-assisted organosolv pretreatment of wood waste using glycerol as solvent was conducted in a commercial microwave reactor with varying temperature of 120-240 degrees C for reducing nitrogen content. The elemental analysis shows that up to 88.1 % of nitrogen and 92.9 % of alkali and alkaline earth metals in wood waste can be removed by microwave-assisted glycerolysis. The solid nuclear magnetic resonance spectrometry analysis illustrate that the urea-formaldehyde resin, lignin and hemicellulose fractions in wood waste can also be simultaneously reduced by pretreatment. Raw and pretreated wood waste was subsequently fast pyrolyzed in a semi-batch pyroprobe reactor. The experimental results demonstrate that the relative content of levoglucosan in pyrolysis vapors was significantly enhanced by pretreatment, whereas the relative content of nitrogen-containing compounds was reduced obviously. These findings provide a simple and efficient pretreatment method for reducing the formation of nitrogenous compounds during fast pyrolysis of nitrogen-rich wood waste.
