Abstract
In this present investigation, textiles samples of non-polymeric nature, e.g, cotton, silk etc. of Indian origin were pyrolysed in a 50 mm diameter and 640 mm long packed bed pyrolyser placed in a tubular furnace from 573K to 1173K in a nitrogen atmosphere. Experiments were designed to investigate the effects of temperature of pyrolysis on yields of char, pyro-oil and gas and their characteristics. A kinetic scheme has been proposed where two parallel reactions occur simultaneously to produce volatiles and char. The kinetic rate constants of both the reactions have been determined in the temperature range under study. The activation energies and pre-exponential factors of all products (solid reactant, volatile and char) have been determined. A mathematical model for the pyrolysis of textile waste has been developed using the kinetic parameters determined under the present study. Calorific values of pyro-oil and char obtained at different temperature have been determined. The structural characteristics of char at different temperatures of 573, 873 and 1173K has also been analysed using SEM.
