“…The other production method of BTX is the hydrodealkylation of C9+ aromatics in the presence of a variety of catalysts such as metal oxides and zeolite catalysts [4][5][6][7]. Among studied catalysts, chrome-based catalysts are the most promising catalyst and mostly used in commercial processes [8,9]. Hydrodealkylation of alkyl-aromatics over Cr2O3/Al2O3 is carried under high hydrogen atmosphere (60-70 10 5 Pa) at high temperatures (T> 600 o C) in order to removal of methyl groups on aromatic rings.…”

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.
