Abstract:

A theoretical analysis has been made of the Sabatier reaction as a means of converting CO2 to H2O. The problems associated with reaction rate, heat removal, reaction stability and optimum performance are discussed. A simplified method for rating catalysts based on the reaction run away or ignition temperature is described. For the Sabatier reaction a critical temperature between 400 and 600 F is desirable. The reaction order and activiation energy have been measured for two catalysts, 0.5 Ru and 0.5 Rh, each on 18 in. alumina. A computer program has been developed to provide design criteria for Sabatier reactors. It is shown that a hybrid reactor involving an ignition start-up followed by an equilibrium cooling curve to a final equilibrium temperature between 500 and 600 F is optimum.
