Abstract Green waste (GW), a typical biomass waste, was used to produce hydrochar using microwave hydrothermal carbonization (MHTC). The results indicate that MHTC promotes the dehydration of GW to a greater extent than traditional oven or oil bath heating under the same hydrothermal conditions. The hydrochar obtained from the MHTC process showed an energy densification factor of 1.27 and a fuel ratio of 0.19, both of which exceeded those produced by traditional hydrothermal processes. Thermogravimetric data also demonstrated that hydrochar obtained using MHTC had better incineration properties. Moreover, the material possessed a high specific surface area and a more porous structure, resulting in improved adsorption properties. The result of value and potential evaluation demonstrated that the MHTC process also displays the lower energy consumption of operation. Hydrochar generated from GW is a potential environmentally friendly functional material, and MHTC appears to be a suitable means of producing this substance.

绿色垃圾微波水热碳化制备改良水炭

摘要 绿色废弃物（GW）是一种典型的生物质废弃物，可用于微波水热碳化（MHTC）生产水炭。结果表明，在相同的水热条件下，MHTC比传统的烘箱或油浴加热在更大程度上促进了GW的脱水。从 MHTC 工艺获得的水炭显示出 1.27 的能量密度因子和 0.19 的燃料比，这两者都超过了传统水热工艺生产的那些。热重数据还表明，使用 MHTC 获得的水焦具有更好的焚烧性能。此外，该材料具有高比表面积和更多孔结构，从而提高了吸附性能。价值和潜力评估结果表明，MHTC工艺还显示出较低的运行能耗。GW 产生的 Hydrochar 是一种潜在的环保功能材料，MHTC 似乎是生产这种物质的合适手段。
