BL2F

About: EU plans for a low-carbon economy require advanced biofuels for aviation and shipping. The EU-funded BL2F project proposes the pioneering integrated hydrothermal liquefaction process at pulp mills to produce drop-in biofuels for aviation and shipping from black liquor. Black liquor is a by-product of the chemical pulping industry that is used as biofuel feedstock, providing 83 % reduction in CO2 emissions compared to fossil fuels and a very competitive production cost per litre. The project proposes three innovations: allowing direct upgrading of HTL-oil by combining salt separation with the HTL reactor; reforming the aqueous phase to hydrogen, decreasing the need for external fossil hydrogen in integrated hydrothermal hydrodeoxygenation; and integrating the process into the pulp mill, leading to treatment cost reductions.
