1Thermodynamic behaviors of Cu in interaction with chlorine, sulfur, phosphorus and minerals during sewage sludge co-incineration显示文摘Thermodynamic equilibrium calculations were performed to reveal effects of interactions among Cl, S, P and other minerals on Cu migration. Our results showed that HCl(g), SO2(g) and(P_2O_5)_2(g) were released from the sewage sludge co-incineration. Cl was found to weaken adsorption of Cu by Al_2O_3, CaO and Fe_2O_3, while S delayed reactions of Fe_2O_3 and Al_2O_3 with Cu, with P having no effect on reactions between the minerals and Cu.Among the coupled systems of Cl, S and P, the co-existences of Cl and S, and Cl, S and P were determined to inhibit Cu volatilization, and the co-existence of Cl and P had an enhancing effect. Cu migration was affected only by S in the S and P system. With the SiO_2, CaO and Al_2O_3 system, both Cl alone and Cl and P led to failed reactions between the minerals and Cu. In the systems of S, S and Cl, S and P, and S, Cl and P, the migration behavior of Cu was mainly affected by S at low temperatures and by Cl at high temperatures, whereas P had no effect on Cu migration during the entire process.Jingyong Liu Chao Liu Guang Sun Wuming Xie Xiao'e Dang Jiahong Kuo Kenlin Chang Jian Sun Shuiyu Sun Musa Buyukada Fatih Evrendilek 2018Chinese Journal of Chemical Engineering2018,26,5:3
2Thermal behaviors, combustion mechanisms,evolved gasses, and ash analysis of spent potlining for a hazardous waste management显示文摘An unavoidable but reusable waste so as to enhance a more circular waste utilization has been spent potlining(SPL) generated by the aluminum industry.The combustion mechanisms, evolved gasses, and ash properties of SPL were characterized dynamically in response to the elevated temperature and heating rates.Differential scanning calorimetric(DSC) results indicated an exothermic reaction behavior probably able to meet the energy needs of various industrial applications.The reaction mechanisms for the SPL combustion were best described using the 1.5-, 3-and 2.5-order reaction models.Fluoride volatilization rate of the flue gas was estimated at 2.24%.The SPL combustion emitted CO_(2), HNCO, NO, and NO_(2) but SO_(x).The joint optimization of remaining mass, derivative thermogravimetry, and derivative DSC was achieved with the optimal temperature and heating rate combination of 783.5 ℃, and 5 ℃/min, respectively.Interaction between temperature and heating rate exerted the strongest and weakest impact on DSC and remaining mass, respectively.The fluorine mainly as the formation of substantial NaF and CaF_(2) in the residual ash.Besides,the composition and effect of environment of residual solid were evaluated.The ash slagging tendency and its mineral deposition mechanisms were elucidated in terms of turning SPL waste into a benign input to a circular waste utilization.Guang Sun Gang Zhang Jingyong Liu Deniz Eren Evrendilek Musa Buyukada 2021Journal of Environmental Sciences2021,33,9:1
