Pyrolysis Characteristics of Waste Fishing Rope
E-mail:
Pyrolysis characteristics of waste fishing rope were investigated by thermogravimetric analysis (TGA). Pyrolysis started at 320 ℃, with the main region of decomposition of the waste fishing rope occurring at temperatures between 370 and 460 ℃. The corresponding kinetic parameters, including the activation energy and pre-exponential factor, were determined by using the differential method over the degree of conversions. The values of activation energies were between 166 and 272 kJ/mol when the conversion of the pyrolysis reaction increased from 5 to 95%. The order of the pre-exponential factor was 109~1017, according to conversion variations. Waste fishing rope was pyrolyzed in a micro-scale tubing reactor at temperatures between 430 and 450 ℃ for 100 to 200 min. As the reaction temperature increased, the yields of pyrolyzed gas and oil increased. The number of carbon atoms in the produced oil was mostly below C15, and a selectivity for C7 hydrocarbno compounds was confirmed.
