This article reviews the hydrothermal liquefaction of biomass with the aim of describing the current status of the technology. Hydrothermal liquefaction is a medium-temperature, high-pressure thermochemical process, which produces a liquid product, often called bio-oil or bi-crude. During the...

Renewable fuels are major alternatives to conventional fossil fuels. Biomass in the form of agricultural and industrial residues is fast becoming popular among new renewable energy sources. Hydrothermal liquefaction can thermochemically convert biomass residues into bio-oil. This work...

Over 40% of the total energy consumed in Europe is used for the generation of heat for either domestic or industrial purposes. Meanwhile, the demand for cooling is steadily increasing in all European Member State. In this context, it is essential to identify the heating and cooling demand in the...

Methanolysis of muskmelon seed oil was optimized employing RSM (response surface methodology). Four process variables were evaluated at two levels: methanol/oil molar ratio (3:1–12:1), catalyst concentration in relation to oil mass (0.25–1.25wt % KOH), reaction temperature (25–65°C) and...

Mediterranean countries generate large amounts of olive oil byproducts mainly OMWW (olive mill wastewater) and EOSW (exhausted olive solid waste). Although solid residues have various valorization strategies, there is no economically viable solution for the OMWW disposal. This study aims to...
