Biomass coming from lignocellulose (crops and forest residues) as well as municipal wastes is currently considered the most readily available alternative carbon source for advanced biofuel and raw chemicals production because of its abundance, low cost, and the fact that it does not compete with the food sector. Several processes have been developed to convert biomass into a liquid energy carrier, known as bio-oil, and fast pyrolysis is one of the most efficient and cost-effective alternatives. Pyrolysis bio-oil can be used for heating, electricity generation, and chemicals production. However, its direct use as transport fuel is limited as a consequence of its high content of water and oxygenated organic compounds (carboxylic acids, phenolic derivatives, aldehydes, sugars, lignin oligomers, etc.), which results in some undesirable properties, such as low heating value, high corrosivity and viscosity, and a significant tendency to polymerize during storage. For that, pyrolysis bio-oils should undergo an upgrading process to achieve transportation fuel specifications. In this context, catalytic fast pyrolysis, catalytic hydrodeoxygenation, and catalytic fast hydropyrolysis are considered the most promising technologies to obtain high quality products from biomass. With this background, the present Special Issue covers new advances of research in the described areas, including novel catalysts development, catalyst deactivation/regeneration studies, new upgrading chemistry and reactors design, large scale implementation, etc., and all manuscripts with outstanding results in this fields are welcome to be submitted.

Abstract: Hydrodeoxygenation (HDO) of levulinic acid aldol condensation products (dimers) was studied with Ru catalyst supported on mesoporous zirconia between 250 and 300 °C and 50 bar H2 in a batch reactor. During the reaction, the unsaturated dimers (containing ketone group and double bonds) were hydrogenated to saturated dimers. A greater degree of deoxygenation was achieved at higher temperatures, and oxygen was removed as water and CO2. Oxygen removal was evidenced by elemental analysis and infrared spectroscopy, in which the C=O peak decreased with increasing temperature. The drawback of high reaction temperature (300 °C) was the minor degree of oligomerization through condensation. Moreover, formation of aromatics was also observed at the higher temperatures. Aside of the saturated dimers, volatile products were obtained at all temperatures, including ketones, acids and esters. This study demonstrates for the first time the potential of LA dimers as a route from lignocellulosic biomass to sustainable biofuels and biocomponents.
