✦ Synopsis

Cocurrent downflow circulating fluidized-bed (or downer) reactors have been proposed as a better alternative to upflow riser reactors for certain types of chemical reactions where a short contact time is required and the intermediate is the desired product, given the uniform flow structure and the greatly reduced gas and solids dispersion in the axial direction observed in the downers
