Description

The pathway is capable of using water as a medium to convert cellulosic biomass into bio-jet oil under reaction conditions of 250-550 °C and 5-25 MPa. Hydrothermal liquefaction technology is mainly divided into two stages, namely biomass liquefaction and bio-oil hydrogenation stage. When utilizing the LCA data set for hydrothermal liquefaction of biomass jet fuel, it is critical that users allocate environmental impact values prudently. The dataset requires energy allocation for proper accounting, where the impacts are divided proportionally based on the energy content of the jet fuel and other ancillary fuels produced. Specifically, the allocation should reflect the energy content per megajoule of jet fuel production. Methodological attention should also be given to analyzing the complete two-stage process - biomass liquefaction and bio-oil hydrogenation - to ensure a full life cycle assessment. Users must consider technological applicability assumptions, especially when generalizing the data for different scales or contexts outside the provided parameters.
