Promoter ile modifiye edilmiş Cr-Al2O3 yüzeyinde mezitilenin benzen, toluen ve ksilene hidrodealkilasyonu n-dekanın varlığında çalışılmıştır. Cr-Al2O3 katalizörünün aktivitesine ve stabilitesine, reaksiyon sıcaklığının, WHSV, krom impregnasyonunun tür ve miktarı ve V, Cs, Ni ve Mo gibi promoterların etkisi incelenmiştir. N-dekanın mezitilene eklenmesi, metil ve etil radikallerinin ortamda bulunmasıyla, Cr-Al2O3 katalizörünün hidrodealkilasyon aktivitesini artırdı. V ve Cs ile modifiye edilmiş katalizör (V-Cs-Cr-Al2O3), stabilite, ürün seçiciliği ve girdi dönüşümü için ticari Pyrotol (Houdry, USA) katalizörü ile karşılaştırılabilir performans gösterdi.

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.
