Hydrothermal carbonization (HTC) is a novel thermochemical conversion process to convert lignocellulosic biomass into value-added products. HTC processes were studied using two different biomass feedstocks: corn stalk and Tamarix ramosissima. The treatment brought an increase of the higher heating values up to 29.2 and 28.4 MJ/kg for corn stalk and T. ramosissima, respectively, corresponding to an increase of 66.8% and 58.3% as compared to those for the raw materials. The resulting lignite-like solid products contained mainly lignin with a high degree of aromatization and a large amount of oxygen-containing groups. Liquid products extracted with ethyl acetate were analyzed by gas chromatography-mass spectrometry. The identified degradation products were phenolic compounds and furan derivatives, which may be desirable feedstocks for biodiesel and chemical production. Based on these results, HTC is considered to be a potential treatment in a lignocellulosic biomass refinery.
水热碳化（HTC）是一种将木质纤维素生物质转化为增值产品的新型热化学转化工艺。使用两种不同的生物质原料：玉米秸秆和柽柳，对 HTC 工艺进行了研究。处理后，玉米秸秆和柽柳的高位发热量分别提高了 29.2 和 28.4 MJ/kg，分别比原料提高了 66.8%和 58.3%。所得的类褐煤固体产物主要含有高度芳构化和大量含氧基团的木质素。用乙酸乙酯提取的液体产物通过气相色谱-质谱进行了分析。鉴定出的降解产物为酚类化合物和呋喃衍生物，它们可能是生物柴油和化学品生产的理想原料。基于这些结果，HTC 被认为是木质纤维素生物质精炼厂的一种潜在处理方法。
