Abstract
Abstract
The high activated γ-Al2O3 hydrodynamic properties in the fixed bed are studied in this paper. The factors of gas velocity and the heights of the bed on the axial bed pressure, bed pressure drop and bed voidage are studied. The results indicated that under the same height of fixed bed, the axial pressure decreased along the bed at the same gas velocity. While the pressure drop increased with the gas velocity and the bed height increased. The pressure drop has a good agreement to the Ergun equation. According to the Ergun equation, the bed voidage is regressed at different height of fixed bed. The results revealed that the bed voidage of high-activated γ-Al2O3 is almost the same in the fixed bed heights of 400 mm, 300mm and 200mm, which is 0.31, 0.32, and 0.32 respectively.
