Production of fuel range oxygenates by supercritical hydrothermal liquefaction of lignocellulosic model systems

Analytical Methods for Fuel Oxygenates

A Concise Background on Fuel Oxygenates Fuel oxygenates are oxygencontaining compounds (e.g., ethers and alcohols) that are added to gasoline either to boost the octane rating, to make the fuel burn cleaner by increasing the oxygen content, or to achieve a combination of both. The most commonly used oxygenates are methyl tertiary-butyl ether (MTBE) and ethanol. Other oxygenates include tertiary...

Hydrothermal Liquefaction of Food Waste and Model Food Waste Compounds

Solid waste is generated at a rate of more than 4 lb per person per day. A significant portion of the non-recyclable waste is food waste, with high water content and low energy density. While most thermochemical conversion processes require a relatively dry feedstock, hydrothermal liquefaction uses subcritical water as the reaction medium and is therefore compatible with high-moisture feedstock...

Hydrothermal and Acid Pretreatments Improve Ethanol Production from Lignocellulosic Biomasses

Hydrothermal and acid pretreatments using different acid charges (1.5%, 3.0%, and 4.5% H2SO4) were proposed for eucalyptus, sugarcane bagasse, and sugarcane straw prior to their bioconversion into ethanol using the semi-simultaneous saccharification and fermentation (SSSF) process. The hydrothermal and acid pretreatments were efficient for hemicelluloses removal from eucalyptus (63 to 96%), bag...
