doi:10.11799/ce202402026

Abstract

Abstract: In order to relieve the pressure of waste PVC treatment and recover hydrocarbon resources, the waste PVC was added to pulverized coal to prepare waste PVC-coal slurry. The morphorlogy and specific surface area of the prepared waste PVC-coal slurry were determined using SEM-EDX and BET, repectively. The influencing mehcainnsms of the added PVC in slurry performance were investigated. The combustion characteristic index and kinetic parameters of raw coal slurry and waste PVC-coal slurry were evaluated by thermoweight analysis method and Coats-Redfern integration method. The results show that the waste PVC can improve the slurry concentration but reduce the stability. Addition of the waste PVC exhibits a synergistic effect on coal slurry combustion. When the amount of waste PVC added is 5%, the positive synergistic effect is the strongest, the burnout rate of coal slurry is the largest, the comprehensive combustion performance is the best, and the apparent activation energy is the largest.
