Abstract
Thermodynamic analysis of equilibrium products and heat requirements is conducted for C8H18 (octane), CH4O (methanol), C2H6O (ethanol) and C3H8 (propane) at specified temperature and pressure. The equilibrium calculation utilizes the NASA equilibrium code by Gordon and MacBride. The temperature range is from 600 to 1700 K, and the pressure is set at 1 bar. The equilibrium calculation shows that the adiabatic temperatures are generally below 1300 K, except for C2H6O and C3H8 at their respective partial oxidation conditions considered in this paper. Calculation also shows that the presence of H2O in the reactant mixture yields high conversion of H2 at temperature above 1200 K, and above which the H2 mole fraction is relatively independent of the mixture temperature. Negligible C(graphite) is predicted for conditions with temperature above 1200 K.
