Pyrolysis kinetics and characteristics of the mixtures of waste ship lubricating oil and waste fishing rope

초록

Kinetic investigations on the pyrolysis of a mixture of waste ship lubricating oil (WSLO) and waste fishing rope (WTR) were carried out using a thermogravimetric analyzer (TGA) at a heating rate of 0.5 degrees C/min, 1.0 degrees C/min and 2.0 degrees C/min. WSLO and WFR were mainly decomposed at the temperature of range of 400 degrees C to 455 degrees C and 370 degrees C to 410 degrees C, respectively. The WSLO/WFR mixture was mainly decomposed at the temperature range of 3 00 degrees C and 450 degrees C, which is a lower temperature than that for the WSLO or the WFR alone at each heating rate. The ranges of apparent activation energies of the WALO/WFR mixture were between 137 U mol(-1) and 197 U mol(-1) at conversions in the range of 10-95%. The mixture of WSLO and WFR was pyrolyzed in a micro-scale tubing reactor at 440 degrees C for 60 min and 80 min. The yield of pyrolyzed gases increased from 2.13 wt% to 2.29 wt% with reaction time. The selectivity to C-7 hydrocarbons was shown in the pyrolyzed oil of the mixture.
