摘要：
Y-faujasite previously synthesised by hydrothermal crystallisation and used in exchange ions by several elements as cerium, lanthanum, strontium and cobalt showed interesting catalytic activities in toluene disproportionation. Appreciable selectivities with respect to main reactions were also observed. The relationship between the catalytic activity and the selectivity of NaCeY and NaLaY catalysts is investigated. It Was found that cerium cations improve a specific selectivity strongly depending on the catalyst activity.
