Abstract

The kinetics of waste automobile lubricating oil have been studied experimentally and modeled mathematically. Experiments were carried out in the tubing bomb microreactor at a temperature of 420-440 °C and reaction times of 5-50 min. Volatile pyrolysis products were identified and quantitatively determined by gas chromotography. A lump model of combined series and parallel reactions for oil formation is proposed. Conversion data fitted first order kinetics for C5-C11 and C12-C25. The kinetic parameters were determined by nonlinear least-squares regression of the experimental data. These calculated values of the product distribution were found to be in agreement with the experimental data.
