Nanostructural Analysis of Co-Re/γ-Al2O3 Fischer-Tropsch Catalyst by TEM and XRD
Dehghan-Niri, Roya; Tsakoumis, Nikolaos E.; Voronov, Alexey; Holmen, Anders; Holmestad, Randi; Vullum, Per Erik; Borg, Øyvind; Rytter, Erling; Rønning, Magnus; Walmsley, John (Peer reviewed; Journal article, 2022)A rhenium promoted Fischer-Tropsch (FT) cobalt catalyst supported on γ-Al2O3 has been investigated by Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD), before and after reduction. Electron diffraction, ... -
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 ... -
α-alumina as catalyst support in Co Fischer-Tropsch synthesis and the effect of added water; encompassing transient effects
Rytter, Erling; Borg, Øyvind; Enger, Bjørn Christian; Holmen, Anders (Peer reviewed; Journal article, 2019)Three catalyst supports containing from 84 to 100% α-alumina prepared by heat treatment of γ-alumina have been impregnated with cobalt and rhenium. The catalysts were tested for Fischer-Tropsch synthesis (FTS) under dry ...
