ABSTRACT:
A new family of crystalline aluminosilicate zeolites has been synthesized. These zeolites are represented by the empirical formula.in-line-formulae description="In-line Formulae" end="lead"?Mmn+Rr+Al(1-x)ExSiyOzin-line-formulae description="In-line Formulae" end="tail"?where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the propyltrimethylammonium cation and E is a framework element such as gallium. These zeolites are similar to MWW but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out alkylation processes.
