Question 3. A catalytic reformer will be designed to operate isothermally at 1000K with a feed gas mixture containing only CO2 and H2 in a mole ratio of unity. The operating pressure has not yet been chosen. The gas mixture at the outlet is expected to contain CO2,H2,CO and H2O. There is the possibility of deposition of carbon on the catalyst which must be avoided if the catalyst should perform satisfactorily. a. Estimate the gas phase composition if there is no deposition of carbon. b. Calculate the amount of energy to be transferred as heat (in or out) per mole of CO2 fed in order to operate the reactor isothermally at 1000K. Again, assume that there is no carbon deposition. c. Over what range of pressures may carbon deposit on the catalyst? Over what ranges of pressures will it not deposit? d. For an initial ratio of CO2 to H2 of unity, what must be the pressure if exactly 10% of the carbon present in the CO2 fed can precipitate as solid carbon at 1000K
