摘要：In this work, the physicochemical properties of the three phase products (hydrochars, gas and tar) produced by antibiotic mycelial residues (AMR) during the hydrothermal reaction and the CO2 gasification performance of hydrochars were systematically studied. The results showed that the gas products of hydrothermal reaction were mainly CO2, the tar products were mainly N-containing compounds and O-containing compounds, alcohols and acids occupied the main proportion of O-containing compounds. The higher hydrothermal temperature reduced the H:C and O:C atomic ratios, promoted the formation of microcrystalline structures, and enhanced the vibration intensity of surface functional groups on FT-IR spectra. Importantly, the hydrothermal reaction mechanism of AMR was revealed. In addition, with the increase of hydrothermal temperature, the gasification reaction time of hydrochars was extended. The random pore model (RPM) had a good fitting effect on the gasification process of PMR and hydrochars. After hydrothermal carbonization, the activation energy of the samples increased from 55.248 kJ mol- 1 to 172.984 kJ mol- 1.
