Kinetics studies of nano-structured iron catalyst in Fischer-Tropsch synthesis
A nano-structuered iron catalyst for syngas conversion to hydrocarbons in FTS prepared by micro emulsion method. Kinetic parameters od nano- structured iron catalyst in FTS catalysts is studied in a wide range of syngas conversions and compared...
A novel method for fabrication of Fe catalyst used for the synthesis of carbon nanotubes
Carbon nanotubes (CNTs) have been grown by decomposition of propane over a nanocamposite
catalyst by chemical vapour deposition (CVD). The catalyst was prepared from an aluminum/iron
oxide/graphite mixture ...
New LHHW kinetic model for CO2 hydrogenation over iron catalyst
A new Langmuir-Hinshelwood-Hougen-Watson type kinetic model for carbon dioxide hydrogenation reaction over a precipitated Fe/Cu/K catalyst is developed in a continuous spinning basket reactor. A number of possible reaction ...
Fischer–Tropsch Synthesis: New reaction mechanism
Although numerous studies over 70 years concern the mechanism of the fischer -tropsch synthesis this sunject still remains controversial. At present many authors favour the CH2 insertion mechanism as dominant for the F-T ...
Water-gas-shift kinetics over a Fe/Cu/La/Si catalyst in Fischer–Tropsch synthesis
The kinetic modeling of the water-gas-shift (WGS) reaction over a Fe/Cu/La/Si catalyst under Fischer–Tropsch synthesis (FTS) reaction condition was investigated. A number of Langmuir–Hinshelwood–Hougen–Watson type rate ...
Kinetics of the water-gas shift reaction in Fischer-Tropsch synthesis over a nano-structured iron catalyst
Based on formate and direct oxidation mechanisms, three Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic models of the water-gasshift
(WGS) reaction over a nano-structured iron catalyst under Fischer-Tropsch synthesis (FTS) reaction...
