Gas flow patterns and pressure profiles through packed and moving beds with layered burdens have theoretically and experimentally been studied. In the middle region of the beds, periodic behaviours of gas flow correspond with the alternative packings of the beds. In the top and the bottom region, gas flow tends to concentrate to a lower resistant part of the beds. The velocity profiles of gas flow at the inlet part of the beds cannot be described with such a simple expression as a linear equation. Usually, the total pressure drop through the beds is smaller than the estimation based on "parallel-flow model." Flow patterns of gas in the top region of the beds are not very affected by the packing structure of the botttom region of the beds and similarly flow patterns in the bottom region are not affected by the packing of the top region. The third layer imposed in the bottom part of the beds, an inclination of top surface and angles of repose of the packed burdens also have a considerable effect on both pressure profiles and flow patterns through the beds.
