Removal of catalyst fines from fluidized bed effluent in the conversion of oxygenate feedstock

A system comprising:

• an oxygenate feed stream;
• at least one reactor comprising at least one fluidized catalyst bed comprising catalyst particles;
• a product stream comprising catalyst particles and a hydrocarbon consisting of a C5+ gasoline, an olefin, an aromatic, and combinations thereof;
• a reactor inlet constructed and arranged to accept the oxygenate feed stream;
• and
• a plurality of filter units each comprising filter medium that comprises a metal alloy, a sintered metal alloy, or a combination thereof,
• wherein the plurality of filter units are fluidly connected to the at least one reactor and constructed and arranged to convey the product stream through said plurality of filter units to generate a filtered product stream comprising a hydrocarbon selected from the group consisting of a C5+ gasoline, an olefin, an aromatic, and combinations thereof, further having substantially no detectable solid material.
