Research on operating parameters of hydrogen production by ethanol steam reforming
LIU Dongsheng
Abstract：Based on the principle of minimizing Gibbs free energy,the simulation of hydrogen production through ethanol steam reforming is conducted,and the influences of temperature,pressure and the water-alcohol ratio on the reforming reaction are analyzed.The equilibrium amounts of H2,CH4,CO2 and CO are studied under the conditions of temperature ranging from 100 to 1 000℃,pressure ranging from 0.1 to 9.0 MPa and water-alcohol ratio ranging from 1 to 10.The results show that under the conditions selected in the study,based on the H2 production,economic benefits and energy efficiency,the optimal working conditions of the reaction are obtained as a temperature of 700℃,a pressure of atmospheric pressure and a water-alcohol ratio of 7.
