Topsoe and Swedish refiner Preem have completed a co-processing campaign at Preem’s Gothenburg refinery, producing renewable diesel and sustainable aviation fuel as part of efforts to expand lower-carbon fuel production using existing refining infrastructure.
The trial involved processing waste- and residue-based lipids together with conventional refinery feedstocks, demonstrating that existing hydrotreating units can be adapted to support large-scale production of renewable fuels, biofuels international reported.
According to the companies, the campaign highlights the ability of conventional refining assets to integrate renewable feedstocks while reducing the carbon intensity of fuel production.
The initiative supports Preem’s broader strategy to increase renewable fuel output and lower emissions across its product portfolio.
For the project, Topsoe provided its HydroFlex technology, which allows refiners to process biogenic feedstocks within existing refinery systems without requiring major infrastructure modifications.
The companies said the fuels produced during the campaign successfully met required quality specifications for both road transport applications and aviation use.
The completion of the campaign is expected to support future efforts to scale renewable diesel and sustainable aviation fuel production through greater use of existing refinery capacity and feedstock flexibility.
