摘要：
The factors influencing the length of the induction period in ethylbenzene disproportionation over large pore zeolites were systematically investigated using LaNaY zeolites with different degrees of lanthanum exchange. The catalytic behavior was related to the number and strength of the Bronsted acid sites in these catalysts as determined by additional non-catalytic techniques. Mechanistic models which may account for the occurrence of the induction period, the deficit of diethylbenzenes during this period and the distribution of the diethylbenzene isomers are discussed.
