| Zusammenfassung: | Copyright © 2017 Elsevier Ltd. All rights reserved. Co-pyrolysis characteristics of municipal sewage sludge and hazelnut shell blend have been studied in this work. The behavior of co-pyrolysis was researched by a method of multi-heating rates and different blend ratios to analyze thermal decomposition stages. The experimental data of the blended samples in TG-DTG plots were compared with calculated data to investigate the interactions during co-pyrolysis. The bio-chars investigated by SEM and FTIR spectra were used to examine the physical and chemical changes. The results showed there are four thermal decomposition stages during co-pyrolysis, with hydrocarbon transforming to gas evolution in the second and the third stages. The inhibitive interaction occurred between 260 and 400°C and the accelerative interaction occurred between 450 and 900°C during co-pyrolysis. The activation energy of the blended sample was 51.97-178.84kJ/mol in the second stage and 207.04-630.73kJ/mol in the third stage calculated by DAEM |
