The transalkylation of trimethylbenzene with benzene was studied over ferrierite, ZSM-5, mordenite, and over β-type and Y-type zeolite catalysts, and the transalkylation activities were compared. Liquid phase transalkylation was performed with a batch reactor under the conditions of 250°C, 3 MPa, and molar benzene/trimethylbenzene ratio of 1:1. The transalkylation proceeded over mordenite, β-type, and Y-type zeolites, and Y-type zeolite exhibited the highest catalytic activity of the three catalysts. USY-type zeolite, a dealuminated Y-type zeolite, had a higher activity than Y-type zeolite. This result may be due to the formation of mesopores through dealumination. The effect of the activity of the zeolites on the transalkylation was studied using ion (Mg2+, Ca2+, Sr2+, Ba2+)-exchanged Y-type zeolite. The catalytic activity for the transalkylation decreased with lower acidity of the zeolite.
