摘要	Co-pyrolysis of pine sawdust with aluminum dross (AD) for harvesting energy product and safely treated ADbiochar composite was investigated in this work. The catalytic pyrolysis experiment was carried out in a fixed bed reactor. The pyrolysis products were analyzed by gas chromatography (GC), gas chromatography coupled with a mass spectrometer (GC-MS), and solid C-13 Nuclear Magnetic Resonance (C-13 NMR). The results show that the heavy metals, such as Cu, were immobilized by organic metal-chelating structures as carbon-oxygen-metal (C-O-M) bonds in the AD-biochar composite. In addition, the hydrogen yield from catalytic pyrolysis of pine on AD reaches 131.86 ml/g, significantly higher than the 98.97 ml/g from pure pine pyrolysis. The enhanced hydrogen production is elaborated by the intermediate hybrid mechanism with formation of C-O-M intermediates between the metallic oxides in AD and the oxygen containing functional groups in biomass. Meanwhile, the CO2 yield decreases from 23.68 ml/g to 16.41 ml/g while the CO yield reduces from 49.72 ml/g to 46.85 ml/g. These results may guide to a new exploration on simultaneous treatment of hazardous industrial wastes and utilization of biomass.
