Abstract

The temperature-programmed desorption(TPD) curves of different gases(CO

H2O

CO2) were measured experimentally for the necessary of engineering application

process optimizing and the study on surface properties of LB energy-saving high temperature shift catalyst.All the curves were decomposed and simulated with the peak fitting module in Origin7.5.Desorption activation energy

pre-exponential factors and reaction orders were calculated by using MATLAB operation platform.The results show that LB catalyst expresses good operating performance at low steam-gas ratio

there are multi-adsorption centers for H2O while not for CO

and there are lower-temperature and higher-temperature absorption centers for CO2 on LB catalyst.Desorption of CO

H2O and CO2 on LB catalyst behaved as one-order reaction.The kinds of absorption centers of LB catalyst and their effect on different gases were discussed.
