ABSTRACT:
Catalyst losses are prevented in riser reactor systems by using a low inlet velocity for the first cyclone separator in each multi-stage cyclone separator in the reactor. Catalyst particles not separated from the product output flow in an oxygenate-to-olefin reactor are also recaptured by cooling the product output flow and passing the flow through an electrostatic precipitator.
