“…Zeolites are well known microporous materials widely used as catalysts in chemical and petrochemical industry due to their large surface areas, shape selectivity, strong acidity and efficient activity [1][2][3][4][5][6][7][8][9][10][11][12]. The physicochemical and catalytic properties of zeolites strongly depend on the number of framework Al atoms present in the zeolite structure.…”

“…Several types of zeolites have been reported to have high activity for benzene alkylation, for example, faujasite, beta, H-ZSM-5, and MCM-22 [1][2][3][4][5][6][7][8][9][10][11]. Elucidation of the reaction mechanism of benzene alkylation on zeolite catalysts is of great interest.…”

“…The main end uses for cumene are for the production of phenolic resins, bisphenol A, and caprolactam. However, 5-10 wt% diisopropylbenzene (DIPB) isomers are produced as low value byproduct during the isopropylation of benzene to cumene (Leu et al, 1990;Sridevi et al, 2001;Reddy et al, 1993). The by-products, DIPB isomers, can be recycled for cumene production, making this process more economical.…”

-In the present study, transalkylation of 1,4-diispropylbenzene (DIPB) with benzene in the presence of modified beta zeolite was performed to produce cumene in a fixed bed reactor. Beta zeolite was exchanged with cerium in order to modify its catalytic activity. Activity of the modified catalyst was evaluated in the range of temperature 493K-593K, space time 4.2 kg h/kmol-9.03 kg h/k mol and benzene/1,4-DIPB molar ratio 1-15 to maximize the reactant conversion and selectivity of cumene. The activity and selectivity of the modified catalyst was found to increase with increase in cerium loading. Maximum selectivity of cumene (83.82%) was achieved at 573 K, benzene/1,4-DIPB 5:1 at one atmosphere pressure. A suitable kinetic model for this reaction was proposed from the product distribution pattern following the Langmuir-Hinshelwood approach. Applying non-linear regression, the model parameters were estimated. The activation energy for the transalkylation reaction was found to be 116.53 kJ/mol.
