摘要： This invention is to a process and system for controlling solids distribution in a gas-solids reactor. Solids distribution is controlled by controlling electrical charges between solid particles flowing between conductive surfaces within a gas-solids reactor. The electrical charges are controlled by conventional means such as by grounding the opposing conductive surfaces, or by applying a voltage to one of the opposing conductive surfaces.

In one embodiment, the process includes providing a plurality of catalyst particles in the reactor, wherein the catalyst particles have a d2 value of greater than about 40 microns. The catalyst particles are contacted with a fluidizing medium under conditions effective to cause the catalyst particles to behave in a fluidized manner and form a fluidized bed. The particles are contacted with one or more primary obstructing members while in the fluidized bed. By fluidizing the catalyst particles in this manner, the catalyst particles can be maintained at an axial gas Peclet number of from about 10 to about 20.

摘要： 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.
