Study on Interaction of Combustible Components of Automotive Shredder Residue During Pyrolysis
The interaction of co-pyrolysis of plastic,textile,leather and sponge,which were typical combustible components of automotive shredding residues,was investigated using thermogravimetry-mass spectrometry(TG-MS)and distributed activation energy model(DAEM).The characteristics of pyrolysis weight loss,kinetics and gas production were discussed.The results indicated that interactions existed among all four components,as evidenced by a comparison of the single-component linear weighted fit data and the mixed pyrolysis experimental data.Specifically,the average activation energy of textile and leather,sponge and plastic,sponge and textile co-pyrolysis decreased by 22.2,25.7 and 33.4 kJ/mol,respectively.In contrast,the average activation energy of sponge and leather co-pyrolysis increased by 7.9 kJ/mol.The participation of sponge could promote the generation of small molecule gases in the mixed sample,while leather,textile and sponge co-pyrolysis could prevent the irregular chain-breaking reaction of plastic to generate small molecule hydrocarbons such as C2H4 and C3H8.
