A 5 cm diameter scale‐down model of a new uniflow cyclone for the ultra‐rapid fluidized (URF) reactor with a gas residence time under 20 milliseconds has been tested at high solids loading (5/1 wt. solids/wt. gas) under cold modeling conditions. The body length, gas exit diameter and amount of gas withdrawn with the existing solids (gas underflow) were varied to obtain high separation efficiency (over 99.9%). Silica sand of 55 and 105 micrometer Sauter mean diameter was used. Grade efficiency curves were determined for several specific configurations to get a deeper understanding of the mechanisms influencing the separation.
