In this paper, the random pore model and the parallel cross -linked pore model have been used to calculate the effectiveness factors of WB- 2 and B109 high temperature shift catalysts.

1%,respectively,when the water vapor and scattering factor are considered.

6%,respectively,when water vapor and scattering factor were considered.

Results showed that Thiele modulus reduced the substrate concentration in the particle and decreased the effectiveness factor;the product inhibiti.

The effectiveness factor of catalyst capsule equals to the product of η s and η c.

The apparent kinetics of the hydrolysis of methyl acetate is studied and the effectiveness factors are tested for different capsule size under different conditions.

By establishing two dimensional physical and mathematical transmission models,the concept of efficiency factor was introduced for taking into consideration the function of turbulent flow spreading and electric wind,and a reverse calculation method was used for identification of parameters with computer.

Based on thermal analysis, calculating methods for determining the overall heat loss coefficient, the efficiency factor and the heat removal factor of heat pipe evacuated tubular collector are presented.
