One-pot transformation of lignocellulosic biomass into crude bio-oil with metal chlorides via hydrothermal and supercritical ethanol processing.

Grape seeds were deconstructed in both hydrothermal and supercritical ethanol media with a combination of two metal chlorides (TiCl:MgCl) to produce bio-oils. The use of metal chloride additives in supercritical ethanol achieved the highest bio-oil yield of 49.2 wt% (300 °C, 30 min).

Ethanol: A Promising Green Solvent for the Deconstruction of Lignocellulose.

Growing energy demand, environmental impact, energy security issues, and rural economic development have encouraged the development of sustainable renewable fuels. Nonfood lignocellulosic biomass is a suitable source for sustainable energy because the biomass feedstocks are low cost, abundant, and carbon neutral. Recent thermochemical conversion studies are frequently directed at converting biomass into high-quality liquid fuel precursors or chemicals in a single step.

Hydrothermal liquefaction of cornelian cherry stones for bio-oil production.

Hydrothermal liquefaction of cornelian cherry stones, fruit processing wastes, was performed at 200, 250 and 300°C with residence times of 0, 15, and 30min. The highest total bio-oil yield was obtained at both 250 and 300°C for the shortest residence time (0min) and found to be 28wt.%.
