摘要: The kinetic parameters of water–gas shift (WGS) reaction in the Fischer–Tropsch synthesis (FTS) on lanthanum-promoted iron catalyst are analyzed by size-dependent thermodynamic method. A Langmuir–Hinshelwood equation is considered for catalysts activity evaluation. series unsupported with different particle sizes prepared via microemulsion These results show that size has considerable effects reactants adsorption and WGS pass from a maximum increasing size. Finally, analysis data showed 14 to 41 nm, activation energies heats carbon monoxide water increased 68 83, 22 28 75 94 kJ/mol, respectively.
