摘要: Abstract The improvement of dechlorination efficiency remains an important challenge during co-hydrothermal carbonization (co-HTC) polyvinyl chloride (PVC). In this work, co-HTC biomass and PVC at different mixing ratios (30%–70%) feed-water pH (3–11) was proposed to further improve the efficiency. terms water solvent, process (87.83%–93.63%) higher than that individual HTC (87.44%). case organic acid/alkali solvents, increased 95.20% pH = 5. Particularly, hydrochars derived from showed high fuel ratio (0.71–0.99) their heating value reached approximately 29.16–32.83 MJ/kg. TGA results combustion behaviors got better compared with hydrochar PVC. Therefore, can realize sustainable utilization towards clean solid fuels. This work also sheds light on potential acid in treatment.
