Metallophosphate molecular sieves, method of preparation and use

A hydrocarbon conversion process for the alkylation of aromatics comprising contacting a stream comprising aromatic compounds with an alkylating agent with a catalyst at hydrocarbon conversion conditions to generate at least one alkylated aromatic compound, wherein the catalyst comprises a microporous crystalline AlPO-67 material, where AlPO-67 has a three-dimensional framework of EO2−, PO2+and at least one of [M2+O2]2− and SiO2 tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of:

• RrMm2+EPxSiyOz
• where M is at least one framework cation of valence 2+ selected from the group consisting of alkaline earth and transition metals, “m” is the mole ratio of M to E and varies from 0 to about 1.0, R is an organoammonium cation selected from the group of ethyltrimethylammonium (ETMA+), diethyldimethylammonium (DEDMA+), and mixtures thereof, “r” is the mole ratio of R to E and has a value of about 0.1 to about 2.0, E is a trivalent element selected from the group consisting of aluminum, gallium, iron, boron and mixtures thereof, “x” is the mole ratio of P to E and varies from 0.5 to about 2.0, “y” is the mole ratio of Si to E and varies from 0 to about 1.0, “m”+“y”≧0.02, and “z” is the mole ratio of O to E and has a value determined by the equation:
• z=(2·m+r+3+5·x+4·y)/2
• and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A1:
