Hydrothermal liquefaction (HTL) and supercritical water gasification (SCWG), two effective thermochemical approaches converting biomass into biofuels, have received increasing attention due to their advantages of a fast reaction rate and the use of wet feedstocks without the need for an energy-intensive drying process. In this review, we first summarize the physical properties of the biocrude oil obtained from HTL and then examine the catalytic hydrotreatment of the biocrude oil with or without solvents. The experimental studies on the SCWG of sewage sludge, microalgae, black liquor, and food wastes are analyzed, and the corrosion and salt-deposition problems associated with the solutions are discussed. Finally, to fully comprehend the reaction mechanism of biomass components in hydrothermal media, the conversion of model compounds (cellulose, hemicellulose, lignin, lipid, protein, and their derivatives) is reviewed.

生物质和模型化合物的水热液化和气化：综述

水热液化（HTL）和超临界水气化（SCWG）是将生物质转化为生物燃料的两种有效热化学方法，由于它们具有反应速度快和无需使用大量能源即可使用湿原料的优点，因此受到越来越多的关注。处理。在这篇综述中，我们首先总结了从HTL获得的生物原油的物理性质，然后研究了有或没有溶剂的生物原油的催化加氢处理。分析了污水污泥，微藻类，黑液和食物垃圾的SCWG的实验研究，并讨论了与溶液有关的腐蚀和盐分沉积问题。最后，为了充分理解水热介质中生物质组分的反应机理，需要对模型化合物（纤维素，
