摘要
1. A catalyst containing by weight : a) from 10 to 99.99% of a mordenite adsorbing molecules of a kinetic diameter larger than about 6.6x10**-10 m, having a Si/Al atomic ratio from about 5 to 50, a sodium content by weight lower than 0.2% of the total weight of dry mordenite, a volume V of elementary mesh from 2.73 to 2.78 cubic nanometers, a benzene adsorption capacity of more than 5% by weight with respect to the dry mordenite weight, said mordenite being in major part shaped as needles, b) from 0 to 89.99% of a matrix selected from the group consisting of alumina, silica, magnesia, zirconia, natural clays or mixtures thereof, c) from 0.005 to 15% of at least one metal from group VIII of the periodic classification of elements, and d) from 0.005 to 10% of at least one metal group IVA of the periodic classification, selected from the group consisting of tin, germanium and lead.
