Rezumat: DOI: 10.24193/subbchem.2019.4.01 Published Online: 2019-12-20 Published Print: 2019-12-30 pp. 7-18 VIEW PDF: PDF This article presents the mathematical model of mass balance, the mathematical model at equilibrium for steam methane reforming process and the analysis of the equilibrium model for different operating conditions (T, P, Xfeed). The optimal operating conditions were established based on the analysis of the equilibrium model. It was also developed the mathematical model of heat balance, while the optimal size of catalyst granules was determined. The optimal working conditions were set by the equilibrium process’ analysis, the reactor feed ratio, H2O:CH4, 3:1, the temperature in the range of 780-1140 K and the pressure of about 30 atm. Keywords: steam methane reforming, mathematical modeling, stoichiometric independent reaction, equilibrium process analysis |
