EFFECT OF HYDROTHERMAL CARBONIZATION TEMPERATURE ON FUEL PROPERTIES AND COMBUSTION BEHAVIOR OF HIGH-ASH CORN AND RICE STRAW HYDROCHAR

ABSTRACT
Hydrothermal carbonization has been proven to improve the fuel properties of low-ash straw biomass. To explore the effect of hydrothermal carbonization on high-ash straw biomass, the fuel properties and combustion behavior of hydrochar prepared by high-ash rice straw and corn straw at different temperature were studied. The results showed that increased reaction temperature could improve the C content, fixed carbon, heating value, and fuel ratios (FC/VM) in high-ash straw hydrochars, which is similar to the change trend of low-ash biomass. The hydrochar prepared at 260°C has similar H/C and O/C atomic ratios and FC/VM to lignite. In addition, the highest energetic recovery efficiency is obtained at 200°C. While at 180°C, the comprehensive combustion characteristic index of the hydrochar is the best, which is 5.04 ⋅ 10–11 [min–2K–3] and 6.42 ⋅ 10–11 [min–2K–3]. In addition, the C content in the hydrochars at 180°C was lower than the raw material, and the ash content increases with the reaction temperature, which is quite different from the low-ash biomass. In conclusion, the hydrothermal carbonization could improve the fuel quality of high-ash straw, while its ash content remains at a high level.
