Modelling and experimental investigation of waste tyre pyrolysis process in a laboratory reactor

Leszek Rudniak , Piotr M. Machniewski

Abstract

A mathematical model of waste tyre pyrolysis process is developed in this work. Tyre material decomposition based on a simplified reaction mechanism leading to main product lumps: noncondensable (gas), condensable (pyrolytic oil) and solid (char). The model takes into account kinetics of heat and mass transfer in the grain of the shredded rubber material as well as surrounding gas phase. The main reaction routes were modelled as the pseudo-first order reactions with rate constant calculated from the Arrhenius type equation with parameter values obtained by fitting the experimental results obtained in our laboratory reactor. The model was implemented within the CFD software (ANSYS FLUENT). The results of numerical simulation of the pyrolysis process are in satisfactory comparison with the experimentally measured mass loss of the tyre sample during pyrolysis process investigated in a laboratory reactor.
