Co-combustion of textile dyeing sludge with cattle manure: Assessment of thermal behavior, gaseous products, and ash characteristics
Zhang, Junhui; Sun, Guang; Liu, Jingyong; Evrendilek, Fatih; Büyükada, Musa (Elsevier Sci Ltd, 2020)Not only can the incineration provide an effective waste stream reduction, but also it enhances the energy recovery. However, the combustion performance of textile dyeing sludge is poor due to its low combustible content ... -
Co-pyrolytic mechanisms, kinetics, emissions and products of biomass and sewage sludge in N-2, CO2 and mixed atmospheres
Chen, Jiacong; Zhang, Junhui; Liu, Jingyong; He, Yao; Evrendilek, Fatih; Büyükada, Musa; Xie, Wuming (Elsevier Science Sa, 2020)The co-pyrolysis technology of the second-generation feedstocks has both engineering and environmental advantages towards resource recovery, waste stream reduction, and energy generation. However, there exists a large ... -
Comparative (co-)pyrolytic performances and by-products of textile dyeing sludge and cattle manure: Deeper insights from Py-GC/MS, TG-FTIR, 2D-COS and PCA analyses
Zhang, Junhui; Zou, Huihuang; Liu, Jingyong; Evrendilek, Fatih; Xie, Wuming; He, Yao; Büyükada, Musa (Elsevier, 2021)Not only does pyrolysis recover energy and value-added by-products but also reduces waste stream volume. The low volatiles and high ash contents of textile dyeing sludge (TDS) limit its mono-pyrolysis performance. This ... -
Coupled mechanisms of reaction kinetics, gas emissions, and ash mineral transformations during combustion of AlCl3-conditioned textile dyeing sludge
Zhang, Junhui; Chen, Jiacong; Liu, Jingyong; Xie, Wuming; Evrendilek, Fatih; Li, Weixin (Elsevier, 2021)Though commonly used in the dewatering of textile dyeing sludge (TDS) before its incineration, chemical conditioning has yet to be evaluated in terms of its impact on the reaction mechanisms, emissions, and ash minerals. ... -
Kinetics, thermodynamics, gas evolution and empirical optimization of cattle manure combustion in air and oxy-fuel atmospheres
Zhang, Junhui; Liu, Jingyong; Evrendilek, Fatih; Xie, Wuming; Kuo, Jiahong; Zhang, Xiaochun; Büyükada, Musa (Pergamon-Elsevier Science Ltd, 2019)Thermogravimetric (TG) and TG-Fourier transform infrared (FTIR) analyses were performed to quantify the comparative performances of cattle manure combustion in air (N-2/O-2) and oxy-fuel (CO2/O-2) atmospheres at four heating ... -
Pyrolytic behaviors, kinetics, decomposition mechanisms, product distributions and joint optimization of Lentinus edodes stipe
Zou, Huihuang; Zhang, Junhui; Liu, Jingyong; Büyükada, Musa; Evrendilek, Fatih; Liang, Guanjie (Pergamon-Elsevier Science Ltd, 2020)The pyrolytic behaviors, kinetics, decomposition mechanisms and product distributions and joint optimization of Lentinus edodes stipe (LES) were quantified. Its main pyrolysis stages (the decomposition of hemicellulose) ... -
TG-FTIR and Py-GC/MS analyses of pyrolysis behaviors and products of cattle manure in CO2 and N-2 atmospheres: Kinetic, thermodynamic, and machine-learning models
Zhang, Junhui; Liu, Jingyong; Evrendilek, Fatih; Zhang, Xiaochun; Buyukada, Musa (Pergamon-Elsevier Science Ltd, 2019)The increased amounts of manure have become an issue of environmental management due to the rapid growth of livestock industry. This study quantified the pyrolytic performance and gaseous products of cattle manure using ... -
Thermal conversion behaviors and products of spent mushroom substrate in CO2 and N-2 atmospheres: Kinetic, thermodynamic, TG and Py-GC/MS analyses
Huang, Jianli; Zhang, Junhui; Liu, Jingyong; Xie, Wuming; Kuo, Jiahong; Chang, Kenlin; Buyukada, Musa (Elsevier, 2019)This study aims at characterizing pyrolysis/gasification behaviors and products of spent mushroom substrate (SMS) in the CO2 and N-2 atmospheres. The major decomposition stages occurred between 200 and 600 degrees C with ... -
Thermodynamic equilibrium simulations of thallium distributions in interactions with chlorine, sulfur, phosphorus, and minerals during sludge co-combustion
Liu, Jingyong; Zhang, Junhui; Sun, Guang; Büyükada, Musa; Evrendilek, Fatih; Dang, Xiaoe (Springer, 2020)Effects of interactions among chlorine (Cl), sulfur (S), phosphorus (P), and minerals on thallium (Tl) distributions were simulated using thermodynamic equilibrium conditions during the sludge co-combustion. Our results ...
