Hydrothermal carbonization (HTC) is an important thermochemical process where biomass is converted into coal-like solid products known as hydrochars. The HTC process is performed in hot-compressed water under self-generated pressures. In this work, the HTC of acorn shells was conducted at various temperatures and reaction times with and without boric acid (H3BO3). A high degree of carbonization occurred at 250 °C in non-catalytic and catalytic 4-h runs. Hydrochars obtained from non-catalytic and catalytic runs at 250 °C consisted of spherically carbon particles with diameters ranging from 303 nm to 3.27 μm. Carbon spheres at 200 and 225 °C for 2 h were not observed. The yield and carbon content of the hydrochars were slightly increased by reuse of the process water in thermal runs without catalysts.

使用和不使用硼酸的木质纤维素生物质生产水炭

水热碳化 (HTC) 是一种重要的热化学过程,其中生物质被转化为称为水炭的类似煤的固体产品。HTC 工艺是在自生压力下的热压缩水中进行的。在这项工作中,橡子壳的 HTC 在不同的温度和反应时间下进行,有和没有硼酸 (H 3 BO 3)。在非催化和催化 4 小时运行中,在 250 °C 发生高度碳化。在 250 °C 下从非催化和催化运行中获得的水炭由直径范围为 303 nm 至 3.27 μm 的球形碳颗粒组成。未观察到在 200 和 225 °C 下 2 小时的碳球。通过在没有催化剂的热运行中重复使用工艺水,水炭的产率和碳含量略有增加。
