In this paper, a thermodynamic analysis of Combined CO2 and O2 reforming of methane, using the
Gibbs free energy minimization method, has been carried out. Mathematical relationship
Lagrange’s undetermined multipliers was applieded and nonelinear equations system was
obtained. The nonlinear programming model was implemented and the MATLAB (MATLAB
7.80, R2009a)solver was used to solve the equations. The thermodynamic equilibriums of the
combined CO2 and O2 reforming of methane are abviously affected by CH4:CO2:O2 feed ratios and
operating temperatures. Optimized conditions for CH4 conversion, hydrogen and monoxide
production are temperatures between 1000 to 1100 K and best CH4:CO2:O2 feed ratio are within
the range of 1:1:0.2–1:1:0.4
