Kinetics of the Fischer–Tropsch reaction in fixed-bed reactor over a nano-structured Fe–Co–Ce catalyst supported with SiO 2

Synergistic Effect of Fe–Co Bimetallic Catalyst on FTS and WGS Activity in the Fischer–Tropsch Process: A Kinetic Study

“…This also means that the water inhibition did not significantly affect the FT rate. The result corroborates the Mirzaei and co-workers − results, where the H 2 O inhibition term was not present in their models for FT kinetics over Fe–Co–Mn, Fe–Co–Ni, and Co–Ni bimetallic catalysts. Water inhibition was not evident in most of the models derived for the cobalt-based catalysts. ,,,, Krishnamurthy et al and Botes studied the effect of water on the kinetics of the FTS reaction over a cobalt-based catalyst and found that the water does not inhibit the reaction.…”

“…Kinetic modeling of this reaction over bimetallic catalysts has been performed by very few authors. Mirzaei and co-workers have developed a model for the FT reaction over Fe–Co–Mn, Fe–Co–Ni, and Co–Ni catalysts. ,− They developed a number of models for the FT reaction based on various monomer formations and carbon chain distribution pathways and concluded that the value of kinetic parameters and activation energy can be attributed to different catalyst preparation methods and active phases of compounded catalysts which imply that mechanism. The role of different phases of iron and cobalt and their impact on the CO adsorption and consumption are not discussed in detail in the literature.…”

Catalytic conversion of natural gas and methane to synthesis gas and beyond: A collection of published research (2009–2015)

“…This complex behavior of the catalyst relative to its particle size is consistent with the Sabatier principle. Eshraghi et al (2015) identified the kinetic behavior of carbon monoxide hydrogenation over a SiO 2 -supported nano-structured Fe-Co-Ce catalyst in a fixed-bed F-T reactor. The conditions considered experimentally were: temperature of 523.15 to 603.15 o K; pressure of 2 to 10 bar; H2/CO feed ratio of 1:1; and, gas hourly space velocity of 4500 h -1 .…”

Modeling Selectivity of Ethylene and Propylene in the Fischer-Tropsch Synthesis with Artificial Neural Network and Response Surface Methodology

“…One of the ways is GTL technology (Gas To Liquid) that natural gas is first converted to synthesis gas (a mixture of hydrogen and carbon monoxide) and then converted into the valuable products such as olefins, gasoline, diesel, kerosene and methanol. Fischer‐Tropsch synthesis is one of the important chemical processes for the production of hydrocarbons including light olefins . The main products are ethylene and propylene which have a higher value‐added than petrochemical substrates such as gas and oil.…”
