- W675533 abstract "The kinetics of the methanation of CO2 in H2 on a supported nickel catalyst have been measured at partial pressures of CO2 below 0.02 atm and at atmospheric pressure and at temperatures between 200 and 230 °C. The methanation of CO was studied in the same concentration range, between 170 and 210 °C. The results can be described by rather simple Langmuir-type rate equations: rCO2 = 1.36 × 1012 · exp(−25 300RT) · pCO2(1+1270 · pCO2)mol hr−1 g−1 and rCO = 2.09 × 105 · exp(−10 100RT) · pCO(1+4.56 × 10−4 · exp (+12 400RT) · pCO)2mol hr−1 g−1 Experiments at 200 °C show that CO poisons the methanation of CO2 in concentrations larger than 200 ppm. Water and methane in small concentrations have no effect on the reaction rate. The results of this study are in good agreement with data published previously. Some mechanistic implications of the kinetic data are discussed." @default.
