Abstract:
1. A process for alkylating aromatic hydrocarbons comprising contacting a hydrocarbon feedstock comprising at least one alkylatable aromatic and a stream comprising at least one olefin having from 2 to about 6 carbon atoms with a catalyst at alkylation conditions and producing an alkylated aromatic product wherein the catalyst comprises a UZM-37 microporous crystalline zeolite having 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 sodium or 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 2, R is a singly charged propyltrimethylammonium cation, “r” is the mole ratio of R to (Al+E) and has a value of about 0.25 to about 3.0, 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 8 to about 40 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: is thermally stable up to a temperature of at least 600° C. and has a BET surface area of less than about 420 m
