【Abstract】 The macrokinetic rate of shift reaction over the commercial size B_110-2 catalyst has been determined in an internal recycle gradientless reactor under atmospheric pressure. The experimental conditions are as follows: temperature of catalyst bed 330-450℃; the composition of reaction gas （dry basis, mole fraction）: CO 0.1-0.35, CO₂ 0-0.35; the ratio of steam to dry gas: 0.3-1.0. A six-parameter rate equation was suggested as follows and the parameters were estimated by means of nonlinear least square method:R=-dN_co/dW=6.076×10⁷exp （-76483/R_gT） P_co^0.952P_H2O^0.217P_CO2^-0.468·P_H2^-0.037（1-β）In the meantime, a simplified four-parameter rate equation was also obtained which was proved in good agreement with the six-parameter equation:R=-dN_co/dW=7.399×10⁶ exp （-78086/R_gT） P_coP_co2^-0.5（1-β）更多还原
