This approach provides new insights into the valorization of wood pyrolysis bio-oils through co-processing with crude oils or by direct incorporation in fuels for marine transportation, contributing to a significant reduction of the carbon footprint of these products. Similar to water-crude oil systems, asphaltenes can form a rigid film at the bio-oil / petroleum-derived oil interface, thus limiting droplets coalescence and increasing the emulsion lifetime without requiring additional emulsifier. The evolution of the interfacial layers with the asphaltene content and the nature of the petroleum-derived oil phase were investigated by interfacial rheology. The results show the consolidation of the interfacial layer and the formation of a solid-like film, referred to as “skin” with appropriate asphaltene content and polarity of the oil phase. Changes in the dilational elasticity depend on the asphaltenes aggregation behaviour according to the Yen-Mullins model, and the mechanisms that account for these phenomena are discussed.Lire moins >
