 Non-isothermal pyrolysis of the mixtures of waste automobile lubricating oil and polystyrene in a stirred batch reactorSeung-Soo Kim, Jinsoo Kim, Jong-Ki Jeon, Young-Kwon Park and Chan-Jin Park Renewable Energy, 2013, vol. 54, issue C, 241-247 Abstract: Kinetic tests on pyrolysis of the mixture of waste automobile lubricating oil (WALO) and polystyrene (PS) were carried out with a thermogravimetric analysis (TGA) technique at a heating rate of 0.5 °C/min, 1.0 °C/min and 2.0 °C/min in a stirred batch reactor. WALO and PS were mainly decomposed 400–455 °C and 370–410 °C, respectively. The mixture of WALO and PS, however, was decomposed between 355 °C and 470 °C, and decomposition proceeded in two broad steps. The apparent activation energies for the pyrolysis of WALO/PS mixture were in the range of 176 kJ mol−1–369 kJ mol−1 at various conversions of 1–100%. The effect of heating rate on the product distribution was studied. The carbon number distribution of the produced oil shifted slightly to light hydrocarbons with a decrease in heating rate. The selectivity of hydrocarbons corresponding to the styrene monomer was high for the pyrolysis of the WALO/PS mixture.
