Fisher-Tropsch syntesen (FTS) er en katalytisk prosess hvor syngas omdannes til vann og hydrokarboner som for eksempel lange kjeder av alkaner, alkener og oksygenater. Interessen for FTS har økt på grunn av den økende ...

The density functional calculations presented here elucidate the nature of the interaction between the Co atom and dimer with a polyaromatic hydrocarbon (PAH). The results are analyzed in terms of structural, electronic, ...

Graphene, a 2D monolayer of graphite, has emerged as a novel material in many areas, such as catalysis and energy storage devices. Because of fascinating properties, such as remarkable surface area, superior electric ...

The impact of operating parameters on H2S capture from a syngas mixture by a Mo-promoted Mn-based high-temperature sorbent was investigated. The parameters investigated included temperature, space velocity, H2S concentration ...

Cobalt catalysts are used on a commercial scale to produce synthetic fuels via the Fischer-Tropsch synthesis process. As adsorbed hydrogen atoms are involved in many of the elementary reaction steps that occur on the ...

Catalysts are defined as materials that lowers the activation energy of a reaction, without being consumed. In heterogeneous catalysis they are commonly transitions metals which have been refined to small particles using ...

The global energy situation is changing slowly into new sustainable patterns of production and consumption. However, fossil fuels still lead the world energy outlook, covering more than 80% of the energy mix. Between other ...

The dynamic changes in composition in the near-surface region of a Pd75%Ag25%(100) single crystal were monitored using near-ambient pressure x-ray photoelectron spectroscopy (NAP-XPS) during CO oxidation under oxygen rich ...

Understanding the scaling relations of adsorption energies and activation energies greatly facilitates the computational catalyst design. To reduce the computational cost and guarantee efficiency, improved scaling relations ...
