“… 71 The incline of conversion from 52% to 89% was also occurred on the deoxygenation of oleic acid when the temperature rose from 300 to 350 °C. 72 The optimum yield of palm oil deoxygenation was obtained at 375 °C. 67 Šimáček et al 70 declared that conversion of rapeseed oil increased with the raise of temperature where all reactants as well as intermediates were completely transformed at 310 °C.…”

“…The use of deoxygenation catalysts to produce green diesel is challenging owing to their deactivation during the process and over time. Mohammed et al (2022) studied the stability of a catalyst prepared from apricot seeds, an agricultural waste, in the hydrothermal production of green diesel fuel from WCO. First, the apricot seeds were soaked in H 3 PO 4 and pyrolyzed at 500 °C for 60 min to obtain activated carbon.…”

Sustainable development is imperative, and the worldwide energy production must focus on the transition from petroleum derivatives to biomass-based biofuels and bioproducts to achieve a bio-based economy. The global interest in the processing of waste biomass to obtain bio-based products is continuously increasing. However, biorefineries have not yet been consolidated. The effective conversion of biomass components for the generation of value-added biochemicals and biofuels is a determining factor for the economic success of biorefineries. Therefore, exhaustive research has been performed to consolidate the biorefinery industry. This review summarizes the current advances in liquid biofuel production and solid catalysts prepared from waste biomass, as well as their advantages, drawbacks, and statistical data. It offers an extensive perspective, covering conventional methods and cutting-edge techniques such as biochemical and thermochemical biomass conversion technologies (e.g., hydrolysis, fermentation, pyrolysis, and gasification) to produce bioalcohols, biodiesel, renewable diesel, bio-jet, and bio-oil. In addition, the preparation of heterogeneous catalysts using residual biomass and different synthesis routes and their role in biofuel production were analyzed. This review contributes to the analysis of the importance of identifying and valorizing a wide spectrum of raw materials (i.e., urban, forestry, industrial, and agricultural) that have the potential to be used as catalyst precursors and biofuel feedstock. Finally, a techno-economic analysis, the main challenges, and the future scope of the diverse methods used to prepare biofuels and catalysts are discussed. This review examines numerous aspects from biomass to catalysts, thus providing relevant information for researchers, students, policymakers, and industry experts. Graphical abstract

“…288,506 Various catalysts were usually applied in the HTL of food waste to improve the yield and quality of biooil. 507,508 For example, a supported bimetallic catalyst (Pt−Re/ C) during the HTL of waste lipid promoted the conversion of oleic and stearic acid, and fatty acids to linear alkanes as highquality biofuels. 261 However, Motavaf et al examined the effects of catalysts including supported metals (Ni/C, Pt/C, Ru/C, Pd/C, Ni/SiO 2 −Al 2 O 3 , Pt/Al 2 O 3 , and Ru/Al 2 O 3 ), metal oxides (CaO, Al 2 O 3 , CeO 2 , La 2 O 3 , and SiO 2 ), and salts (acid and base additives) on the HTL of food waste for bio-oil production.…”

“…During the catalytic HTL process for upgrading protein-containing biomass, the catalyst, Ru/C, was added to reduce the heteroatom content of bio-oil, leading to a high heating value in comparison to those of noncatalytic HTL products . Additionally, other additives such as potassium phosphates and cosolvent ethanol have been tested to increase the bio-oil yield with increasing quality for energy applications. , Various catalysts were usually applied in the HTL of food waste to improve the yield and quality of bio-oil. , For example, a supported bimetallic catalyst (Pt–Re/C) during the HTL of waste lipid promoted the conversion of oleic and stearic acid, and fatty acids to linear alkanes as high-quality biofuels .

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.
