Conclusions
-
1.
Catalytic properties of zeolite-Y samples with different contents of calcium and REE cations were studied in the process of alkylation of benzene with ethylene. A high catalytic activity was shown for samples prepared by a simultaneous calcium and REE exchange and for samples prepared by a successive exchange but containing high concentrations of REE.
-
2.
A correlation was found between acidity, adsorption heats of benzene, and acidity of all catalyst samples studied.
