Abstract
The invention provides low metal content molecular sieve catalyst compositions, processes for making such catalysts, and processes for using such catalysts in the conversion of an oxygenate into one or more light olefins. Preferably, the catalyst composition comprises a matrix material having a low metal content. By utilizing matrix materials having low metal contents, the amount of metal-catalyzed side reaction byproducts formed in a reaction system, particularly in an oxygenate-to-olefin reaction system, can be advantageously reduced.
