Alkane Influence of Combustion Products in Polyethylene and Gasoline

To study the influence of fire residues between gasoline and polymeric materials, it discussed the types and characteristics of Polyethylene (PE) combustion produce on different stages, according to its pyrolytic process after burning, and then compared with combustion residues of gasoline. The results shown that the combustion produces of PE on different burning stages were mainly contained C10∼C16 linear alkenes, which were different from gasoline on the characteristics and distribution. Though it would be interference with gasoline on composition in material evidence identification, but also can be distinguished by careful analysis.
