Functionalization of lignocellulosic derivatives towards biomaterials or biofuels

Résumé

Faced with depleting fossil fuel reserves, and ever-increasing demand for energy, chemicals and materials, the valorization of renewable resources such as lignocellulosic biomass has become essential. The main components of lignocellulose, lignin and cellulose, can be valorized in various ways into different platform chemicals by depolymerization. However, we are often confronted with very complex product charges containing mixtures of monomers and oligomers, whose separation and characterization must be optimized [1-3]. The obtention of fuel-like components is linked with the development of stable and resistant catalysts able to selectively transform those derivatives. But the use of these bio-polymers directly as material precursors for polymer or other type of industry is also attracting the attention of researchers. In this presentation, we will present and compare several approaches to the valorization of lignin into materials applications. The first targeted application is the production of polyols for the synthesis of non-polyurethane (NIPU) polymers by the incorporation of lignin oligomers having high OH density [4]; the second one is the production of bio-binder for bitumen in combination with used cooking oils (UCO). It consists in the functionalization of lignin or cellulose in order to increase lipophilicity and reach interesting rheological properties by mixing with UCO [5]. Finally, we will also present and discuss the possible catalytic pathways from lignocellulose to sustainable aviation fuels (SAF) that are highly desirable to decarbonize aviation industry.
