文摘

The solid residence time distribution was calculated using a tracer technique. The axial and radial structures of the bed materials were affected by the direction of the gas jets. The direction of the gas jets affected the solid residence time distribution. Appropriate directions of the gas jets were identified for particular chemical reactions.
