CIRCULATING FLUIDIZED-BED AS A CATALYTIC REACTOR - EXPERIMENTAL-STUDY

In recent years, the circulating fluidized bed as a reactor has experi enced increasing application in industry. A circulating fluidized bed (CFB) has some unique features as a chemical reactor. The performance of the CFB reactor was investigated in a 0.25-m-dia. riser system with ozone decomposition in the reactor. Both axial and radial profiles of ozone concentration are presented, as well as overall conversions und er various reaction conditions. The effects of the operating condition s on the performance of the CFB reactor were examined. The experimenta l results show that the performance of a circulating bed as a reactor is much nearer to that of a well-mixed system than that of a plug-flow system. The effectiveness factor of the reactor seems to decrease wit h increase of solids holdup in the reactor.
