摘要: The present invention is directed to a large-pore aluminosilicate molecular sieve comprising alumina and silica, where the ratio of SiO2/Al2O3 ranges from about 75 to 600, and its method of preparation. The large-pore aluminosilicate molecular sieve of the present invention has the ability to catalyze reactions involving particularly bulky transition states or large molecules.

摘要: As synthesized by conventional technique, zeolite ZSM-11 is crystallized in the presence of substantial amount of at least one of the quaternary cations of a Group VA element of the Periodic Table of Elements. When synthesized in the conventional way, ZSM-11 contains said cations as well as substantial amount of sodium ions. To obtain a more catalytically active form of ZSM-11, the sodium ions must be exchanged to very low levels. By synthesizing zeolite ZSM-11 according to the present method, i.e. in the presence of one or more alkylenediamines having from 7 to 12 carbon atoms and with a specifically defined reaction mixture composition, ZSM-11 having different organic cations but the same crystal structure as conventionally prepared ZSM-11 is obtained. The ZSM-11 prepared in accordance hereto is very low in sodium content as synthesized.

摘要: A new and useful improvement in the method for preparing synthetic crystalline aluminosilicate zeolite ZSM-35 is provided. The improved method comprises synthesizing zeolite ZSM-35 in the presence of butanediamine as template rather than the conventional template of ethylenediamine or pyrrolidine. Not only is synthesis of zeolite ZSM-35 facilitated by the present improved method, but the zeolite product is substantially more pure than that obtained by the conventional method of synthesis. Further, catalysts made with the zeolite ZSM-35 synthesized in accordance hereto are much more catalytically active than those obtained by the conventional synthesis method.
