Hydrophobic Catalyst Support Surfaces by Silylation of γ-Alumina for Co/Re Fischer-Tropsch Synthesis
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 ... -
The impact of sequential H2-CO-H2 activation treatment on the structure and performance of cobalt based catalysts for the Fischer-Tropsch synthesis
Patanou, Eleni; Tsakoumis, Nikolaos; Myrstad, Rune; Blekkan, Edd Anders (Journal article; Peer reviewed, 2018) -
Water as key to activity and selectivity in Co Fischer-Tropsch synthesis: γ-alumina based structure-performance relationships
Rytter, Erling; Borg, Øyvind; Tsakoumis, Nikolaos; Holmen, Anders (Peer reviewed; Journal article, 2018)Thirteen γ-alumina supports with different pore sizes and pore size distributions have been impregnated with cobalt and rhenium. The catalysts were tested for Fischer-Tropsch synthesis (FTS) under dry and enhanced water ... -
X-ray absorption, X-ray diffraction and electron microscopy study of spent cobalt based catalyst in semi-commercial scale Fischer-Tropsch synthesis
Tsakoumis, Nikolaos; Dehghan-Niri, Roya; Rønning, Magnus; Walmsley, John; Borg, Øyvind; Rytter, Erling; Holmen, Anders (Peer reviewed; Journal article, 2014)Calcined, reduced and spent Co-Re/γ-Al2O3 catalysts for Fischer–Tropsch synthesis (FTS) were characterized and compared. Co-K-edge and Re-LIII-edge X-ray absorption near edge structure (XANES), X-ray powder diffraction ...
