Abstract：The effects of inlet pressure,superficial gas velocity and superficial solid velocity on the voidage of pressured moving bed were investigated experimentally.When superficial solid velocity or the superficial gas velocity stays the same,the voidage decreases with the increase of the inlet pressure.However,when the inlet pressure remains constant,the superficial solid velocity superficial gas velocity have little influence on the voidage.It is found that the voidage can be calculated by ε=0.32+0.04067/Pin+With the fitting formula of voidage and Ergun equation,the pressure drop can be conveniently calculated.The maximum deviation between the calculated values and experimental data is less than ±10％.
