Abstract
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 sets originated from the combination of formate mechanism for water gas shift reaction and enolic mechanism for Fischer-Tropsch synthesis with various rate determining states are considered. This results show that the CO2 hydrogenation process is limited by the reaction between surface CO and hydrogen species to form enolic (HCO) units. This surface reaction is the key reaction step in producing of higher hydrocarbons via Fischer-Tropsch synthesis.
