摘要：
Hydrothermal liquefaction technology can convert lignocellulosic biomass such as straws into bio-oil, and it can be upgraded to produce liquid fuels and high value-added chemicals. But it is accompanied by inherent drawbacks, such as high oxygen content and high viscosity. Thus, it is crucial to develop upgrading method which can be suitable for bio-oils with variable composition. In recent years, the facile method for bio-oil upgrading by zero-valent metals (Al, Fe, Mg and Zn) as an international burgeoning technology is proposed, that has superiority in material adaptability, cost and efficiency. In this paper, the principle, classification and research progress of in-situ hydrogenation of bio-oils by metal hydrolysis are systematically reviewed. Combined with the numerical simulation method, the main problems of in-situ hydrogenation of bio-oils by metal hydrolysis are analyzed and the research directions are proposed. The role of active hydrogen and hydrogen gas in bio-oil in-situ hydrodeoxygenation upgrading is still not clear. The successful cooperation of hydrogenation catalyst and metal/metallic oxide plays an important role in in-situ hydrodeoxygenation upgrading process. The mechanism of hydrothermal liquefaction and upgrading should be further investigated by theoretical calculations, such as lumping kinetics and molecular simulation. © 2021, Editorial Board of CIESC Journal.
