acetone Catalytic conversion of cumene in both fluidized and packed beds of catalyst were reported. catalyst C,H, +0, CHOH+(CH),0+C cumene phenol In very dilute cumene-air mixtures the kinetics are essentially first-order reversible with respect to cumene with an equilibrium conversion of 94%. In packed bed experiments (Hm = 76.2 mm) using downflow of gas (uo = 64 mds) the conversion of cumene was found to be 60%. However, with upflow of gas at the same flow rate in the same bed, the solids fluidize (Umf = 6.1 mmls) and bubbles of gas were observed roughly 13.5 mm in diameter. What conversion do you expect to find under these conditions? Estimated values: & = 0.4, D = 24 10-mº xs,&r=0.5, a=0.33 1Emi ' mf M cumene-air
