Abstract Compared to riser reactors, downer reactors have reduced gas and solids segregation and more uniform flow structure which enhance the gas–solids contacting efficiency and eventually result in more uniform product distributions within shorter residence times. However, little research has been reported on the entrance region and/or on the effect of distributor design, although this is a very important issue. In this study, a cold model downer unit (9.3 m tall and 0.10 m i.d.) with three… CONTINUE READING
