Biomass acid-catalyzed liquefaction – Catalysts performance and polyhydric alcohol influence
نویسندگان
چکیده
Herein, the data acquired regarding the preliminary experiments conducted with different catalyst, as well as with two polyhydric alcohols (glycerol and 2-ethylhexanol), for the preparation biooils from cork liquefaction at 160 °C, is disclosed. This data may be helpful for those who intent to outline a liquefaction procedure avoiding, thus, high number of experiments.

متن کاملDirectional liquefaction of biomass for phenolic compounds and in situ hydrodeoxygenation upgrading of phenolics using bifunctional catalysts
Phenolic compounds derived from biomass are important feedstocks for the sustainable production of hydrocarbon biofuels. Hydrodeoxygenation is an effective process to remove oxygen-containing functionalities in phenolic compounds. This paper reported a simple method for producing hydrocarbons by liquefying biomass and upgrading liquefied products. Three phenolic compounds fractions (1#, 2#, and...
