Mg-Fe-mixed oxides derived from layered double hydroxides: A study of the surface properties [PDF]

Journal of the Serbian Chemical Society, 2011
The influence of surface properties on the selectivity of the synthesized catalysts was studied, considering that their selectivity towards particular hydrocarbons is crucial for their overall activity in the chosen Fischer- -Tropsch reaction ...

Iron supported on beaded carbon black as active, selective and stable catalyst for direct CO2 to olefin conversion

Catalysis Communications, 2023
The Fischer-Tropsch-to-Olefins process allows to convert waste stemming CO2 with green hydrogen to olefins. Iron can catalyse both core reactions: 1) reverse-water-gas-shift as well as 2) Fischer-Tropsch.

Initiation: A Critical Step for High Activity and Stability in Ni‐Based Methane Dry Reforming Catalysts Supported on θ‐Al2O3

Angewandte Chemie, EarlyView.
A well‐defined Ni/θ‐Al2O3 catalyst prepared by surface organometallic chemistry exhibits sharp temperature‐dependent behavior in dry reforming of methane. At 850°C, a dynamic induction process forms a transient carbide‐like NiCx phase that enables continuous carbon removal and coke resistance, whereas at 800°C incomplete carbon insertion leads to ...

Generation and resource potential of abiogenic alkane gas under organic–inorganic interactions in petroliferous basins

Journal of Natural Gas Geoscience, 2021
The generation mechanism of abiogenic alkane gas and whether the gas has industrial values are the focus of international attention. CH4 generated by Fischer–Tropsch synthesis is an important constitutent of abiogenic alkane gas.

Room‐Temperature Gas‐Phase CO2‐to‐C3 Coupling by a 4f‐Aromatic Cluster

Angewandte Chemie, EarlyView.
We engineered a 4f metalla aromatic cluster, PrB2C2−, that enables efficient sequential C−C coupling with CO2 at room temperature, yielding a linear C3 backbone. This system provides a complete theoretical catalytic cycle and establishes a new design principle for lanthanide mediated CO2 activation.

Factors affecting the extent of branching in fischertropsch synthesis products with iron-based catalysts [PDF]

, 1989
Branched products are mainly formed during secondary isomerization reactions, and not in the main synthesis reaction itself. The extent of branching is a function of the catalyst formulation. High acidity and a low hydrogenation strength of the catalyst (
