AEI-type zeolite, its synthesis and its use in the conversion of oxygenates to olefins |
摘要 |
A crystalline material is described that has an AEI framework type, wherein the material, in its calcined, anhydrous form, has a composition involving the molar relationship: <?in-line-formulae description="In-line Formulae" end="lead"?>(n)X<SUB>2</SUB>O<SUB>3</SUB>:YO<SUB>2</SUB>,<?in-line-formulae description="In-line Formulae" end="tail"?> wherein X is a trivalent element, Y is a tetravalent element n is from 0 to less than 0.01. The material is normally synthesized in a halide, typically a fluoride, medium and exhibits activity and selectivity in the conversion of methanol to lower olefins, especially ethylene and propylene. |
