摘要:
Catalytic cracking processes such as fluidized catalytic cracking, naphtha cracking, and olefin cracking are catalyzed by the UZM-35 family of crystalline aluminosilicate zeolites represented by the empirical formula: Mmn+Rr+Al(1-x)ExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the dimethyldipropylammonium cation and E is a framework element such as gallium. These UZM-35 zeolites are active and selective in the catalytic cracking of hydrocarbons.

Xylene and ethylbenzene isomerization process is catalyzed by the UZM-35 family of crystalline aluminosilicate zeolites represented by the empirical formula: Mmn+Rr+Al(1-x)ExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the dimethyldipropylammonium cation and E is a framework element such as gallium. These UZM-35 zeolites are active and selective in the isomerization of xylenes and ethylbenzene.
摘要:
A new family of crystalline aluminosilicate zeolites has been synthesized. These zeolites are represented by the empirical formula. M1an+Al(1-x)ExSiy′Oz″ where M1 is at least one exchangeable cation selected from the group consisting of alkali, alkaline earth metals, rare earth metals, ammonium ion, hydrogen ion and mixtures thereof, “a” is the mole ratio of M1 to (Al+E), “n” is the weighted average valence of M1, E is an element selected from the group consisting of gallium, iron, boron, and mixtures thereof, “x” is the mole fraction of E, y′ is the mole ratio of Si to (Al+E), and z″ is the mole ratio of O to (Al+E). These zeolites are similar to MCM-68 but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out various hydrocarbon conversion processes.
摘要:
A new family of crystalline aluminosilicate zeolitic compositions, UZM-35 compositions, has been synthesized. These zeolitic compositions are represented by the empirical formula. Mmn+Rr+Al1-xExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the dimethyldipropylammonium cation and E is a framework element such as gallium. These compositions comprise a MSE zeolite, a MFI zeolite and an ERI zeolite. The compositions are similar to MCM-68 but are characterized by unique x-ray diffraction patterns and have catalytic properties for carrying out various hydrocarbon conversion processes.
