“…Ru based catalysts have shown high performance to reduce levulinic acid or its esters to GVL (Hengne et al, 2012). XPS studies revealed that a higher extent of Ru 0 species in case of carbon supported Ru could account for its higher hydrogenation activity as compared to Ru on other supports.…”

Lignocellulosic biomass provides an attractive source of renewable carbon that can be sustainably converted into chemicals and fuels. Hydrodeoxygenation (HDO) processes have recently received considerable attention to upgrade biomass-derived feedstocks into liquid transportation fuels. The selection and design of HDO catalysts plays an important role to determine the success of the process. This review has been aimed to emphasize recent developments on HDO catalysts in effective transformations of biomass-derived platform molecules into hydrocarbon fuels with reduced oxygen content and improved H/C ratios. Liquid hydrocarbon fuels can be obtained by combining oxygen removal processes (e.g. dehydration, hydrogenation, hydrogenolysis, decarbonylation etc.) as well as by increasing the molecular weight via C-C coupling reactions (e.g. aldol condensation, ketonization, oligomerization, hydroxyalkylation etc.). Fundamentals and mechanistic aspects of the use of HDO catalysts in deoxygenation reactions will also be discussed.

“…These initial results are highly promising since significantly more harsh reaction conditions (200°C, 30-40 bar H 2 ) are generally reported in the literature for these reactions to achieve similar yields of γ-valerolactone with catalysts containing transition metals like Pt, Ru and Rh. 29,30,35,36 More detailed exploration of the γ-valerolactone formation from methyl levulinate and derivatives will be the subject of future work.…”

“…Among them, Ru catalysts shown high performance to reduce levulinic acid or its esters 59 to GVL. Thus, Manzer 60 showed that GVL can be obtained with 97 % yield by hydrogenation of levulinic acid in dioxane as a solvent at 423 K with 5 wt% Ru/C, while 99 % yield could be obtained in a continuous process in supercritical CO 2 over a Ru/SiO 2 catalyst.…”

In this work some relevant processes for the preparation of liquid hydrocarbon fuels and fuel additives from cellulose, hemicellulose and triglycerides derived platform molecules are discussed. Thus, it is shown that a series of platform molecules such as levulinic acid, furans, fatty acids and polyols can be converted into a variety of fuel additives through catalytic transformations that include reduction, esterification, etherification, and acetalization reactions. Moreover, we will show that liquid hydrocarbon fuels can be obtained by combining oxygen removal processes (e.g. dehydration, hydrogenolysis, hydrogenation, decarbonylation/descarboxylation etc.) with the adjustment of the molecular weight via C-C coupling reactions (e.g. aldol condensation, hydroxyalkylation, oligomerization, ketonization) of the reactive platform molecules.
