Hydrothermal process is an emerging technology that contributes to sustainable production of biomass-derived chemicals, fuels, and materials. This technology uses hot compressed water to convert various biomass feedstocks including recalcitrant organic compounds in biowastes into desired solid, liquid, and gaseous products. In recent years, considerable progress has been made in the hydrothermal conversion of lignocellulosic as well as nonlignocellulosic biomass to value-added products and bioenergy to fulfill the principles of circular economy. However, it is important to assess hydrothermal processes in terms of their capabilities and limitations from different sustainability aspects so that further advances can be made toward improvement of their technical maturity and commercialization potential. The key aims of this comprehensive review are to (a) explain the inherent properties of biomass feedstocks and physio-chemical characteristics of their bioproducts, (b) elucidate related transformation pathways, (c) clarify the role of hydrothermal process for biomass conversion, (d) evaluate the capability of hydrothermal treatment coupled with other technologies for producing novel chemicals, fuels and materials, (e) explore different sustainability assessments of hydrothermal processes for potential large-scale applications, and (f) offer our perspectives to facilitate the transition from a primarily petro-based to an alternative biobased society in the context of changing climate.

“…In recent years, the solid byproduct (also dened as hydrochar) from HTL and HTG has gained increasing attention. 3,[65][66][67] Regarding HTL, it involves the thermochemical conversion of biomass into biocrude in a hot and pressurized water environment with sufficient residence time. 68 Extensive attention has been paid to bio-crude oils and chemicals from the HTL process, whereas relatively fewer studies have focused on the production of hydrochar.…”

“…[3] Hydrothermal liquefaction (HTL) is a thermochemical process that allows the conversion of wet biomass such as microalgae, avoiding a costly drying step. [4,5] The lipids are hydrolyzed, forming carboxylic acids that can be further converted into drop-in fuels for diesel and jet fuel. [6] Besides, the carbohydrates and proteins can also be converted, affecting the quality and properties of the HTL bio-oil as a function of microalgae biochemical composition.…”

Catalytic Hydrotreatment of Algal HTL Bio‐Oil over Phosphide, Nitride, and Sulfide Catalysts

et al. 2023

Global energy demand and environmental concerns about limiting CO 2 emissions have been growing recently. This is why fuel production from renewable resources has become a priority. In this context, microalgae represent an attractive alternative carbon source. In this work, different supported catalysts, including metal phosphide, nitride, and sulfide, were tested for the hydroconversion of bio-oil issued from the hydrothermal liquefaction of microalgae. Supported Ni phosphide catalysts promoted the decarboxylation and decar-bonylation route, while NiMo nitride promoted the hydrodeoxygenation pathway. NiW sulfide catalysts were the most performant, producing a hydrotreated oil with the best higher heating value (HHV), lower aromaticity degree, and lower average molar mass. Among sulfide catalysts, NiWS/SiO 2 À Al 2 O 3 was the least active, probably due to the inhibition of acid sites by the nitrogen compounds. However, NiWS/Al 2 O 3 performed better, showing high hydrogenation performances, which contributed to the conversion of refractory compounds.
