The present invention provides various processes for fluidizing molecular
sieve catalyst compositions in a fluidized bed reaction system. The
invention comprises fluidizing a molecular sieve catalyst composition
with a reactive fluidizing medium under conditions effective to convert
at least a portion of the fluidizing medium to additional product. The
invention is ideally suited for implementation into an oxygenate to
olefin reaction system, in which the fluidizing medium optionally
comprises byproducts of the oxygenate to olefin conversion reaction.
