Yttrium promoted Ni-based double-layered hydroxides for dry methane reforming
(Journal article; Peer reviewed, 2018)Yttrium modified Ni-based double-layered hydroxides were tested as novel catalysts in dry methane reforming. The catalysts were characterized by XRF, BET analysis, XRD, TPR-H2, TPD-CO2, TGA/DSC-MS, H2 chemisorption and ... -
Zirconia-Supported Catalysts for Oxidation of NO to NO2 in the Production of Nitric Acid
(Master thesis, 2021)Salpetersyre er et viktig kjemisk produkt som hovedsakelig blir brukt til å produsere kunstgjødsel av nitrater. Den industrielle prosessen for framstilling av salpetersyre foregår i tre hovedtrinn, kald Ostwaldprosessen. ... -
ZnO-Carbon-Nanotube Composite Supported Nickel Catalysts for Selective Conversion of Cellulose into Vicinal Diols
(Journal article; Peer reviewed, 2015)A ZnO-nanolayer-coated carbon nanotube (CNT) composite (ZnO–CNT) was employed as a support to immobilise Ni catalysts. Well-mixed oxides, formed as a result of enhanced interfaces between the two oxides on CNTs, resulted ... -
α-alumina as catalyst support in Co Fischer-Tropsch synthesis and the effect of added water; encompassing transient effects
(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 ...
