Abstract

The effect of nano-particle size on the kinetics of water- gas-shift (WGS) reaction on iron based catalyst in Fischer-Tropsch synthesis (FTS) studied in a continuous spinning basket reactor. A series of iron oxide particles with different particle sizes doped by copper and lanthanum prepared as a catalyst. A new Size-dependent kinetic model for WGS reaction is developed by thermodynamic method. Kinetic parameters of model were evaluated by experimental results for iron catalysts with different particle sizes. The results show that the parameters of size-dependent model changed with temperature and catalyst particle size. Surface tension energy (σ) of iron catalyst and size-independent activation energy for WGS reaction is calculated by experimental results. Size independent activation energy for WGS reaction is calculated as 4 kJ/mol base on hematite particles.
