Rytter, Erling; Salman, Ata ul Rauf; Tsakoumis, Nikolaos; Myrstad, Rune; Yang, Jia; Lögdberg, Sara; Holmen, Anders; Rønning, Magnus (Peer reviewed; Journal article, 2018)Eight different silanes with chloro or methoxy active ligands have been examined to modify the surface of a standard γ-alumina support to investigate the effect of surface acidity and hydrophobicity in Fischer-Tropsch ... -
Improving carbon efficiency and profitability of the biomass to liquid process with hydrogen from renewable power
Hillestad, Magne; Ostadi, Mohammad; del Alamo Serrano, Gonzalo; Rytter, Erling; Austbø, Bjørn; Pharoah, Jon; Burheim, Odne Stokke (Journal article; Peer reviewed, 2018)A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept. Based on detailed process models, it is demonstrated that the ... -
