摘要：

A novel kinetic model has been proposed for the thermal pyrolysis of tyres. The model is based on a reaction scheme that considers an intermediate lump and parallel reactions for the formation of the different product lumps. Seven lumps have been taken, which are gas (C-4), non-aromatic liquid (C-5-C), aromatics (C), tar (C11(+)), char (low grade carbon black), intermediate and the original tyre. The kinetic data have been obtained in a pilot plant provided with a conical spouted bed reactor. The inert gas used is nitrogen and the temperature has been varied from 425 to 6 10 degrees C. Discontinuous runs have been carried out for obtaining the kinetic data, and the product stream has been analysed on-line at different reaction times, thereby monitoring the evolution with time of mass fraction of the different components. The kinetic model gives reasonable predictions for lump yields. (c) 2007 Elsevier B.V. All rights reserved.
