    Abstract: A Dy-alumino-silicate catalyst, useful for hydrocarbon conversion reactions, is chemically characterized by the empirical formula Mx(A102)x(SiO2)y.(H2O)z, where x, y and z are integers, the ratio x:y being usually from 1.0 to 0.2 and where at least 25% (and preferably more than 40%) of the negative charge associated with the aluminum of the alumino-silicate framework is satisfied by a cation of Dy or a cation of an oxide or a hydroxide of Dy. Preferably, upon ignition analysis the catalyst will evolve from 1 to 6 molecules of water (typically 1.5-2.5molecules) for each atom of Dy in the catalyst. Typically the negative charge associated with the zeolite framework is not completely satisfied by cations containing Dy and the balance of cations necessary for electronic equivalency comprise H or cations of metals, metal oxides or metal hydroxides. The zeolite also contains less than one alkali metal cation for every four atoms of aluminum in the framework. The zeolite can be amorphous, but preferably is at least partially crystalline and can adsorb benzene.

    Abstract translation: 用于烃转化反应的Dy-铝硅酸盐催化剂的化学特征在于经验式Mx（A102）x（SiO2）y。（H2O）z，其中x，y和z是整数，x：y 通常为1.0至0.2，并且通过Dy阳离子或氧化物或氢氧化物的阳离子满足与铝硅酸盐骨架的铝相关的负电荷的至少25％（优选大于40％） 的Dy。 优选地，在点燃分析时，对于催化剂中的每个Dy原子，催化剂将从1至6分子的水分（通常为1.5-2.5分子）放出。 通常，与沸石骨架相关的负电荷不完全满足含有Dy的阳离子，电子当量所需的阳离子余量包含H +或金属，金属氧化物或金属氢氧化物的阳离子。 沸石在框架中每四个铝原子也含有不到一个碱金属阳离子。 沸石可以是无定形的，但优选至少部分结晶并且可以吸附苯。
