The effect of copper as a chemical promoter on the performance of a cobalt based Fischer-Tropsch synthesis catalyst
… and that the industry is looking at a commercial FT synthesis cobalt catalyst, it is essential to reinvestigate the effect of copper on a cobalt catalyst. Copper has an effect on the overall activity of iron and cobalt [Kolbel, 1951, J. Schwank, 1991], but the reasons are not clearly understood. …

Development of a Kinetic Model for Low Temperature Fischer-Tropsch Synthesis
… as the main source of energy. This requires a shift towards renewable and sustainable alternatives. The well-established FischerTropsch (FT) synthesis is a potential process route to produce liquid fuels and speciality chemicals and address this challenge. FT synthesis is a polymerisation reaction …

Influence of preparation techniques on the Fischer-Tropsch performance of supported cobalt catalysts
Cobalt based catalysts are generally used for the FT synthesis due to their high activity and selectivity for linear hydrocarbons, low activity for the water gas shift reaction and lower price compared to noble metals [22]. There can, however, be a large effective loss of active metal due to strong …

Novel empowered supports for iron-based Fischer-Tropsch in a power-to-liquids process
Fischer-Tropsch (FT) synthesis is a process that converts carbon monoxide and hydrogen into liquid hydrocarbons 1 . In the past, FT synthesis has been used to produce gasoline and diesel from coal and natural gas. However, with increasing demand for renewable and sustainable energy sources, there …

Nitrogen-containing compounds from ammonia co-feed to the Fischer-Tropsch synthesis
The FT synthesis has been used predominantly for production of automotive fuels. This has made the financial benefit from the FT process heavily reliant on crude oil prices. Increasing the financial viability of the process has been achieved by improving production methods, production of …

Model systems for the investigation of metal-support interactions in cobalt based Fischer-Tropsch
… role in the optimization of the Fischer Tropsch (FT) synthesis. Cobalt (Co)-based catalysts have been widely used in low temperature Fischer Tropsch synthesis for the production of longer chain olefins [1]. The interaction between the support and the active metal, Co, has been observed to affect …

[Ca₂₄Al₂₈O₆₄]⁴⁺(e⁻)₄ electride as a novel support system for iron-based Fischer-Tropsch synthesis
Iron-based Fischer-Tropsch (FT) technology is well established in the industrial production of hydrocarbon resources. The use of a stable inorganic electride as a support system, with potential promoter effects which could replace commonly used alkali metals, may have the potential to open a new …

CO AND CO2 HYDROGENATION BY FISCHER TROPSCH SYNTHESIS PROMOTED WITH IRON BASED HETEROGENEOUS CATALYSIS: DATA COLLECTION AND PROCESS DESIGN
… through processes such as Fischer–Tropsch (FT) synthesis. Traditionally, FT relies on syngas (CO/H2) over transition-metal catalysts, but the direct hydrogenation of CO2 has been less explored, particularly with Fe-based heterogeneous catalysts. Iron is an abundant and inexpensive metal, …

Energy Systems Analysis for a Solar Economy
… routes of gasification/Fischer-Tropsch (FT) synthesis and fast-hydropyrolysis/hydrodeoxygenation. For &eta<sub>carbon =70-95%, the synergistic gain of the optimal integrated process is evidenced from the 28-156% lower solar energy consumption compared to augmented gasification/FT …

Effect of ammonia co-feeding on oxygenates over K-Mo2C in the Fischer-Tropsch synthesis
The Fischer-Tropsch (FT) process, producing long chained waxes and transportation fuels, is competing with fuels derived from crude oils and its profitability is therefore dependent on the global oil price. However, increasing the value of synthesized products could render the profitability of the …

Utilization of cobalt catalyst for high temperature Fischer-Tropsch synthesis in a fluidized bed reactor
… catalyst for high temperature Fischer-Tropsch synthesis (HTFT). Cobalt was loaded onto a gamma alumina support, the catalyst was characterized using TPR, BET/BJH, XRD, and PSA to track changes in the catalyst morphology. The reactor was characterized to determine the minimum fluidization …

Perovskites as New Support Materials for the Iron Based Fischer-Tropsch Synthesis
… catalysts for the commercial Fischer-Tropsch synthesis (FTS) employed at PetroSA and Sasol in South Africa [2]. The use of iron catalysts is not only influenced by the low price of the active material compared Co and Ru, but also by higher activity and a wide window of FT operating conditions. …
