It is crucial to develop economical and energy-efficient processes for the sustainable transformation of biomass into fuels and chemicals. In this context, supercritical water biomass valorization (SCBV) processes are an alternative way to produce biogas, biofuels, and valuable chemicals. Supercritical water technology has seen much progress over the last fifteen years and an industrial application has merged: the supercritical water oxidation of wastes. The evolution from lab-scale to pilot-scale facilities has provided data on reaction mechanisms, kinetics, modeling, and reactor technology as well as an important know-how, which can now be exploited to use the reactivity in supercritical water to transform biomass into gases (CO, H(2), CO(2), CH(4), and N(2)) or into liquids (liquid fuel and valuable chemicals) with the supercritical water biomass gasification and liquefaction processes, respectively. This Review highlights the potential of SCBV processes to transform biomass into gas and liquid energy sources and highlights the developments that are still necessary to push this technology onto the market.
开发经济且节能的工艺，以实现生物质向燃料和化学品的可持续转化至关重要。在此背景下，超临界水生物质增值（SCBV）工艺是生产沼气、生物燃料和有价值化学品的一种替代方法。在过去十五年中，超临界水技术取得了很大进展，并且已经出现了工业应用：废物的超临界水氧化。从实验室规模到中试规模设施的发展提供了关于反应机理、动力学、建模和反应器技术的数据以及重要的专门知识，现在可以利用这些来利用超临界水中的反应活性，分别通过超临界水生物质气化和液化工艺将生物质转化为气体（CO、H₂、CO₂、CH₄和N₂）或液体（液体燃料和有价值的化学品）。本综述强调了SCBV工艺将生物质转化为气体和液体能源的潜力，并强调了将该技术推向市场仍需进行的发展。
