Abstract
A biased air distribution grid is used to promote solids entrainment and dense bed internal mixing for the bed material of a fluidized bed reactor. The air distribution grid distributes air at a high velocity zone having a velocity ranging from 11 to 50 feet per second and a low velocity zone having a velocity ranging from 3 to 10 feet per second. The high velocity zone and the low velocity zone provide an improved lateral mixing for the reactor.
