HTL bio-crude is a complex mixture with many different compound classes, and is highly dependent on the feedstock (biomass/organic waste) used for its production as well as on the process conditions. Bio-crude is not suitable for direct use as a transportation fuel, unless proper upgrading is performed. Therefore, the aim of this project is to identify and demonstrate the optimal upgrading pathway for HTL-derived bio-crude and then refining into transport‑grade biofuels. For this purpose, catalytic hydrotreating pathway will be used to produce drop-in biofuels with transport grade properties. In the end, the deoxygenated and nitrogen/sulphur free bio-oil will be eventually obtained. Distillation of such bio-oil will give high quality transport‑grade fuels. Furthermore, the technical suitability of these distilled bio‑oils will also be examined in an actual engine. Additionally, an alternative pathway to utilize existing refinery infra‑structure will be also explored, where the bio‑crude is used as a co-feed in fossil refineries.
