Cumene oxidation kinetics
WebKinetics of transalkylation of diisopropylbenzene were studied over Ca modified YH zeolite catalyst which proved to be a good active catalyst (Grigore et al., 2001). Cumene synthesis over beta zeolite has been reported in the literature (Bellussi et al., 1995; Perego et al., 1996; Smirnov et al., 1997; Halgeri and Das, 1999). WebNov 15, 2001 · The kinetics of cumene oxidation was investigated in a bubble column reactor at different temperatures of the reaction mixture in the range 378−403 K. The Arrhenius parameters of the reaction rate constants of cumene oxidation were determined as a result of solving inverse kinetic problem. Design of cumene oxidation was carried …
