Hydrodealkylation of mesitylene in the presence of n-decane to benzene, toluene, and xylenes (BTX) over the promoted Cr-Al2O3 was studied. The effect of reaction temperature, WHSV, impregnation type, and amount of Cr and promoters such as V, Cs, Ni, and Mo on the stability and activıty of Cr-Al2O3 was investigated. The addition of n-decane to mesitylene accelerated the hydrodealkylation activity of Cr-Al2O3 because of the formation of methyl- and ethyl-radicals. The catalyst modified with V and Cs (V-Cs-Cr-Al2O3) has a comparable performance with the commercial catalyst Pyrotol (Houdry, USA) in terms of stability, product selectivity, and reactant conversions.

“…Dealkylation by breaking the C–C bonds of alkylbenzenes, such as ethyl and propyl benzenes, is most commonly performed in the gas phase using catalysts such as ZSM-5, 10,11 supported Cr 2 O 3 12,13 and metal catalysts. Among these catalysts, Cr 2 O 3 /Al 2 O 3 exhibited high activity for the dealkylation of alkylbenzenes and excellent stability under high reaction temperature.…”

Development of a poly-functional catalyst that has higher hydrodealkylation activity based on 15% Cr/γ -Al 2 O 3 was researched for benzene production from an alkyl-aromatic mixture via hydrodealkylation. For this goal, the effects of the promoters like Fe, Co, or Ni and their concentrations on the activity of a Cr/Al 2 O 3 catalyst were investigated. Toluene + n-heptane + tetrahydrotiophene (89:10:1 w%) model mixture, which has the same content as industrial aromatics, was used as feedstock. The activities of catalysis in reactions of hydrodealkylation, hydrocracking, and hydrogenolize with respect to conversions of toluene, heptane, and tetrahydrotiophene were tested, respectively. As to the obtained results, the catalyst including 5% Fe has a higher hydrodealkylation activity, compared to the catalyst including Co, and especially to the alumocrom catalyst not including a promoter, while it has a lower coke formation and reduced activity to the catalyst including Ni.
