The paper presents a thermodynamic analysis of the methanation of carbon dioxide by hydrogen reduction. Equilibrium gas phase composition was determined by means of parametric equations. Calculations were performed for the temperature range T = 500 – 700 K and the initial composition 
. A crucial parameter for catalytic processes, carbon precipitation range 
was presented as a function of temperature and an initial gas phase CO2-H2 composition. The CO2 conversion efficiency and the methane yield in the process was determined. Obtained results may be used for experimental research prediction and in industrial pragmatic.
