Process for oxygenate to olefin conversion using 2-d pentasil zeolite

A process for the conversion of oxygenates to olefins comprising:

• passing an oxygenate feedstream to an oxygenate conversion reactor operated at oxygenate conversion reaction conditions, wherein the reactor includes a catalyst having an layered pentasil zeolite, to generate a process stream comprising olefins, wherein the catalyst is a zeolite having a microporous crystalline structure comprising a framework of AlO2 and SiO2 tetrahedral units, and an empirical composition in the as synthesized and anhydrous basis expressed by the empirical formula of:
• Mmn+Rrp+AlSiyOz
• where M is at least one exchangeable cation selected from the group consisting of alkali and alkaline earth metals, “m” is the mole ratio of M to Al and varies from 0 to 3, R is at least one organoammonium cation selected from the group consisting of quaternary ammonium cations, diquaternary ammonium cations, “r” is the mole ratio of R to Al and has a value of about 0.1 to about 30, “n” is the weight average valence of M and has a value of about 1 to about 2, “p” is the weighted average valence of R and has a value of about 1 to about 2, “y” is the mole ratio of Si to Al and varies from greater than 32 to about 200 and “z” is the mole ratio of 0 to Al and has a value determined by the equation:
• z=(m·n+r·p+3+4·y)/2.
