The macrokinetics of sulfur-tolerant methanation SDM - 1 4φ5×5 mm catalyst under conditions——0. 30-1. 20MPa
573-673K
H251-54%
CO14-25%
CH42.5-14%
CO2 5. 3-9. 0% and N2 10. 2-13. 4% is studied in a gradientless reactor with internal -recycle. The macrokinetics model is as follows rCH4 = l. 3491 ×10-5exp[- 32777/ (RT) ]p0.83yCO0.51yH20.32rCO2=1.7014×10-6exp[-52311/(RT)]p1.56yCO0.50yH2O(1-β)1.60The kinetics equations are tested by mathematical statistic method and residual distribution. The result shows that the model is reasonable.
