CAScade deoxygenation process using tailored nanoC.. (CASCATBEL)
CAScade deoxygenation process using tailored nanoCATalysts for the production of BiofuELs from lignocellullosic biomass
Date du début: 1 nov. 2013,
Date de fin: 31 oct. 2017
The present project is aimed to the development of a multi-step process for the production of second-generation biofuels from lignocellulosic biomass in a cost-efficient way through the use of tailored nanostructured catalysts. The proposed process is based on the cascade combination of three catalytic transformations: catalytic pyrolysis, intermediate deoxygenation and hydrodeoxygenation. The sequential coupling of catalytic steps will be an essential factor for achieving a progressive and controlled biomass deoxygenation, which is expected to lead to liquid biofuels with a chemical composition and properties similar to those of oil-derived fuels. According to this strategy, the best nanocatalytic system in each step will be selected to deal with the remarkable chemical complexity of lignocellulose pyrolysis products, as well as to optimize the bio-oil yield and properties. Since hydrodeoxygenation (HDO) is outlined in this scheme as the ultimate deoxygenation treatment, the overall hydrogen consumption should be strongly minimized, resulting in a significant improvement of the process economic profitability. The use of nanostructured catalysts will be the key tool for obtaining in each chemical step of the cascade process, the optimum deoxygenation degree, as well as high efficiency, in terms both of matter and energy, minimizing at the same time the possible environmental impacts. The project will involve experiments at laboratory, bench and pilot plant scales, as well as a viability study of its possible commercial application. Thereby, the integrated process will be assessed according to technical, economic, social, safety, toxicological and environmental criteria. The consortium will be formed by 17 partners, including 4 research institutions, 6 universities, 5 large industries and 2 SME.
