摘要：Extremely high volatiles and excessive chlorine contents remained bottlenecks for the conversion of polyvinyl chloride (PVC) into eco-friendly solid fuel. In our work, we proposed the co-hydrothermal treatment (co-HTC) of pomelo peel (PP) and PVC under citric acid solvent at 220 degrees C. Properties of the PP/PVC blended hydrochars were assessed by elemental and proximate analysis, scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET), Fourier transform infrared (FTIR) analysis, thermogravimetric analysis (TGA) and single pellet combustion. In addition, gas chromatography - mass spectrometry (GC-MS) and FTIR were used to analyze the chemical features of process water obtained after the co-HTC process. Results showed that hydrochar obtained after co-hydrothermal carbonization by using 50% PP and 50% PVC (CA-HC-5:5) demonstrated the best higher heating value (22.58 MJkg(-1)), energy yield (51.76%) and dechlorination efficiency (93.50%). Moreover, CA-HC-5:5 was characterized by a finer texture suitable for pelletization, which could be due to PVC particles inserting into the pores of PP. In support of this phenomena, BET results showed that the surface area and quantity of N-2 gas absorbed by PP were significantly reduced when co-treated with PVC. Hence, the results implied that PVC could be effectively co-valorized with lignocellulosic biomass to produce eco-friendly solid fuel. (C) 2021 Elsevier Ltd. All rights reserved.
