| Abstract: | The intrinsic kinetic experiments of water-gas shift reaction over a domestic catalyst of LB type were carried out in an integral micro-reactor under following conditions: 3MPa, 598～728K, and feed gas composition (mole fraction) CO 0.066～0.139, CO2 0.041～0.1, H2 0.262～0.457, H2O 0.217～0.386 and N2 0.077～0.271. A kinetic model of power-law type was developed, and the kinetic model parameters were estimated by means of complex method. The results of statistical and industrial application tests show that this model is high acceptable and reliable. |
