The intrinsic kinetics experiments were conducted at different temperatures

different gas flow rates

different steam/gas ratios and different gas components over LB energy-saving high temperature shift catalyst.This is necessary for industrial application

process optimization and fundamental chemistry research of LB catalyst.The kinetics data were fitted with formate mechanism and power-law models

and the parameters in the models were estimated.Statistical examination showed that the two models were highly acceptable and creditable.Based on the kinetics results

the industrial measurement of LB catalyst used in a large-scale ammonia-synthesis plant was performed.With one-dimension heterogeneous diffusion-reaction model of isothermal spherical catalyst for multicomponent single reaction

the industrial reactor was simulated by using the configuration method and Merson method.The simulated distributions of bed temperature

intraparticle diffusion efficiency factor

CO content and shift ratio with respect to catalyst bed height were obtained

and the distributions agreed with those of industrial measurements.
