The Preparation and Characterization of Co–Ni Nanoparticles and the Testing of a Heterogenized Co–Ni/Alumina Catalyst for CO Hydrogenation
(12/21/2019)
Samples of well-controlled nanoparticles consisting of alloys of cobalt and nickel of different atomic ratios were synthesized using wet chemical methods with oleylamine as the solvent and the reducing agent. These materials ...
Fischer–Tropsch: Product Selectivity–The Fingerprint of Synthetic Fuels
(3/14/2019)
The bulk of the products that were synthesized from Fischer–Tropsch synthesis (FTS) is a wide range (C<sub>1</sub>–C<sub>70+</sub>) of hydrocarbons, primarily straight-chained paraffins. Additional hydrocarbon products, ...
Substitution of Co with Ni in Co/Al2O3 Catalysts for Fischer–Tropsch Synthesis
(3/17/2020)
The effect of cobalt substitution with nickel was investigated for the Fischer–Tropsch synthesis reaction. Catalysts having different Ni/Co ratios were prepared by aqueous incipient wetness co-impregnation, characterized, ...
Influence of Cs Loading on Pt/m-ZrO2 Water–Gas Shift Catalysts
(Catalysts;11(5), 4/29/2021)
Certain alkali metals (Na, K) at targeted loadings have been shown in recent decades to significantly promote the LT-WGS reaction. This occurs at alkali doping levels where a redshift in the C-H band of formate occurs, ...
Hydrocracking of Octacosane and Cobalt Fischer–Tropsch Wax over Nonsulfided NiMo and Pt-Based Catalysts
(9/30/2021)
The effect of activation environment (N<sub>2</sub>, H<sub>2</sub> and H<sub>2</sub>S/H<sub>2</sub>) on the hydrocracking performance of a NiMo/Al catalyst was studied at 380 °C and 3.5 MPa using octacosane (C<sub>28</sub>). ...
Influence of Cs Loading on Pt/m-ZrO2 Water–Gas Shift Catalysts
(4/29/2021)
Certain alkali metals (Na, K) at targeted loadings have been shown in recent decades to significantly promote the LT-WGS reaction. This occurs at alkali doping levels where a redshift in the C-H band of formate occurs, ...
Editorial: Cobalt and Iron Catalysis
(12/27/2019)
Cobalt and iron have long history of importance in the field of catalysis that continues to this day [...]
Low Temperature Water-Gas Shift: Enhancing Stability through Optimizing Rb Loading on Pt/ZrO2
(2/5/2021)
Recent studies have shown that appropriate levels of alkali promotion can significantly improve the rate of low-temperature water gas shift (LT-WGS) on a range of catalysts. At sufficient loadings, the alkali metal can ...
Fischer-Tropsch Synthesis: The Characterization and Testing of Pt-Co/SiO2 Catalysts Prepared with Alternative Cobalt Precursors
(6/1/2021)
Different low-cost cobalt precursors (acetate, chloride) and thermal treatments (air calcination/H<sub>2</sub> reduction versus direct H<sub>2</sub>-activation) were investigated to alter the interaction between cobalt and ...
Fischer-Tropsch Synthesis: Cd, In and Sn Effects on a 15%Co/Al2O3 Catalyst
(10/16/2019)
The effects of 1% of Cd, In and Sn additives on the physicochemical properties and Fischer-Tropsch synthesis (FTS) performance of a 15% Co/Al<sub>2</sub>O<sub>3</sub> catalyst were investigated. The fresh and spent catalysts ...
