Abstract:
1. A process for catalytic cracking comprising contacting a hydrocarbon feedstock with a catalyst at catalytic cracking conditions and producing a cracked product wherein the catalyst comprises a UZM-35 microporous crystalline zeolite, wherein the UZM-35 has a three-dimensional framework of at least AlO 2 and SiO 2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of: where M represents a combination of potassium and sodium exchangeable cations, “m” is the mole ratio of M to (Al+E) and varies from about 0.05 to about 3, R is a singly charged dimethyldipropylammonium cation, “r” is the mole ratio of R to (Al+E) and has a value of about 0.25 to about 2.0, E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof, “x” is the mole fraction of E and has a value from 0 to about 1.0, “y” is the mole ratio of Si to (Al+E) and varies from greater than 2 to about 12 and “z” is the mole ratio of O to (Al+E) and has a value determined by the equation: and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A: and is thermally stable up to a temperature of at least 400° C.
