The work presented in this article addresses the application of hydrothermal carbonization (HTC) to produce a solid fuel named HTC-Biochar, whose characteristics are comparable to brown coal. Several batch HTC experiments were performed using agricultural residues (AR) as substrates, commonly treated in farm-based biogas plants in Germany. Different AR were used in different combinations with other biomass residues. The biogas potential from the resulting process water was also determined. The combination of different AR lead to the production of different qualities of HTC-Biochars as well as different mass and energy yields. Using more lignocellulosic residues lead to higher mass and energy yields for the HTC-Biochar produced. Whilst residues rich in carbohydrates of lower molecular weight such as corn silage and dough residues lead to the production of a HTC-Biochar of better quality and more similar to brown coal. Process water achieved a maximum of 16.3 L CH4/kg FM (fresh matter).
本文介绍了水热碳化（HTC）在生产一种名为 HTC-Biochar 的固体燃料中的应用，该燃料的特性与褐煤相当。使用农业废弃物（AR）作为底物进行了多次批式 HTC 实验，这些农业废弃物在德国的农场沼气厂中通常得到处理。不同的 AR 与其他生物质残渣以不同的组合方式使用。还确定了由此产生的工艺水中的沼气潜力。不同 AR 的组合导致生产出不同质量的 HTC-Biochars 以及不同的质量和能量产率。使用更多的木质纤维素残渣可提高 HTC-Biochar 的质量和能量产率。而富含低分子量碳水化合物的残渣，如玉米青贮料和面团残渣，则可生产出质量更好、更类似于褐煤的 HTC-Biochar。工艺水最高可达到 16.3 L CH4/kg FM（新鲜物质）。
