研究了桉木渣（ER）、造纸污泥（PMS）及其混合物在燃烧过程中的热行为。制备了掺量为10 ~ 90wt%的共混物，研究了它们的共燃行为和动力学。实验在差示热重分析仪中以不同的加热速率（10、20和40 ° C/min）、在120 ° C至950 ° C范围内的温度和在80%氮气/20%氧气气氛中进行。综合特性指数随PMS比例的增加而降低。在PMS中添加ER可以改善PMS的燃烧特性。由Kissinger-Akahira-Sunose（KAS）法和Starink法得到的平均活化能值并没有随着PMS在共混物中所占比例的增加而逐渐下降。当PMS含量为10%时，平均活化能达到最小值，KAS法为159.30 kJ/mol，Starink法为160.36 kJ/mol。(C)2016爱思唯尔有限公司版权所有
The thermal behavior of eucalyptus residues (ER), paper mill sludge (PMS) and their blends during combustion processes was investigated in this study. Blending ranging from 10 wt% to 90 wt% on dosage ratio were prepared to study their co-combustion behaviors and kinetics. The experiments were conducted in a differential thermogravimetric analyzer at different heating rates (10, 20 and 40 degrees C/min), at temperature ranging from 120 degrees C to 950 degrees C and in 80% nitrogen/20% oxygen atmosphere. The comprehensive characteristic index decreased with the increase of the PMS ratio. Adding ER to PMS may improve the combustion characteristics of PMS. The value of average activation energy obtained by Kissinger-Akahira-Sunose (KAS) and Starink methods did not gradually decline with the increasing proportion of PMS in the blends. The average activation energy reached the minimum number when the percentage of PMS was 10%, which was 159.30 kJ/mol by KAS and 160.36 kJ/mol by Starink, respectively. (C) 2016 Elsevier Ltd.
