| Zusammenfassung: | Copyright © 2019 Elsevier Ltd. All rights reserved. In the leather industry, considerable amounts of non-recyclable solid leather wastes (SLWs) are produced and accumulated in factories. In this work, the non-isothermal thermochemical analysis (TGA) test was used to analyse the thermal degradation behaviour of chromium-tanned leather shaving, which is one of the main SLWs. The pyrolysis experiments were carried out under nitrogen atmosphere from 30 to 800 °C at different heating rates of 5, 10, 15 and 20 °C/min. Three different kinetic models, including the Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and Kissinger methods, were used to calculate the kinetic parameters. The activation energy values calculated by FWO and KAS methods were 391.79 and 348.77 kJ/mol, respectively. In consideration of the high HHV (14.15 MJ/kg) and carbon productivity (10.15%), SLWs could represent a potential candidate material for bioenergy production and carbon preparation. These results could be used for the design of thermochemical conversion processes utilizing SLWs as feedstock |
