To optimize the energy yield (EY) of food waste (FW) via hydrothermal carbonization (HTC), a response surface method was applied. Hydrochars and spent liquor were further conducted to evaluate their characterization and anaerobic digestion potential. Results found that optimal parameters for HTC of FW were suggested as temperature of 260 °C, reaction time of 4 h and moisture of 80%, with higher EY of 66.1%. Higher heating value, good combustion quality, lower H/C and O/C ratios indicated that hydrochar could be utilized as a safe solid fuel. Biochemical methane potential (BMP) experiment showed that spent liquor and hydrochars could be used as feedstocks for anaerobic digestion. Interestingly, hydrochars added in the spent liquor could promote the specific methane yield, which was 2.53 times higher than no addition of hydrochars. The finding of this study could provide useful information for HTC of FW and the utilization of hydrochars and spent liquor.
为了通过水热碳化（HTC）优化食物垃圾（FW）的能量产量（EY），应用了响应面法。进一步对水热炭和废水中进行了评估，以评估它们的特性和厌氧消化潜力。结果发现，FW 的 HTC 的最佳参数建议为温度 260°C、反应时间 4 小时和水分 80%，EY 更高达 66.1%。更高的热值、良好的燃烧质量、更低的 H/C 和 O/C 比表明水热炭可用作安全的固体燃料。生物甲烷潜力（BMP）实验表明，废水中和水热炭可用作厌氧消化的原料。有趣的是，在废水中添加水热炭可以提高特定的甲烷产量，比不添加水热炭时高出 2.53 倍。本研究的发现可为 FW 的 HTC 以及水热炭和废水中的利用提供有用信息。
