About the project

Biomass is the main source of renewable carbon, enabling production of a wide variety of valuable energy carriers and chemicals, e.g transportation fuels. Sweden has good prospects for utilizing residual biomass from forest and agricultural land for biofuel production, for example via biomass termochemical conversion in which one criticl step is pyrolysis. In view of the advantage of using existing refinery infrastructure, biomass pyrolysis is a versatile way to produce bio-oil (or bio-crude) that could potentially replace fossil-based feedstock. However, bio-oil’s chemical instability, mainly caused by the high oxygen content, complicates its transportation and storage and constitutes a major hinderance for widespread adoption as feedstock. Removal of oxygen by HDO, hydrodeoxygenation,  is a promising pre-treatment stage necessary for downstream upgrading of the bio-oil to premium products, such as transportation fuels.

Large R&D efforts have been directed towards studying pyrolysis processes for biooil production and upgrading to transportation fuels. But there is a lack of studies considering the integration of different processes/technologies for producing clean hydrogen for the hydrodeoxygenation step for bio-oil upgrading. This project aims at developing and strengthen knowledge about production of biofuels via biomass feedstock pyrolysis and hydrodeoxygenation, including various hydrogen sources, to produce stable bio-oil that can be further upgraded in existing refinery plants to gasoline, diesel and jet fuel. Four different process routes, including also the refinery and – when relevant – CCS (Carbon Capture and Storage) will be investigated. Key performance indicators associated with energy and economic performance and important insights on opportunities and constraints of possible utilization and integration of process routes in existing infrastructure will be provided.
