Moving Bed Hydrocarbon Conversion Process |
摘要 |
Moving bed hydrocarbon conversion processes are provided for contacting a catalyst moving downward through a reaction zone with a hydrocarbon feed, withdrawing the catalyst from the reaction zone and conveying the catalyst to a regeneration zone wherein the catalyst moves downward. The catalyst is withdrawn from the regeneration zone and passed downward to an upper zone of a particle transfer apparatus wherein the transfer of catalyst from the upper zone through an intermediate zone to a lower zone is regulated by varying the pressure of the intermediate zone and the flow rate of gas passing through the valveless conduits. A body within the lower zone is in catalyst communication with a valveless conduit and provides more consistent catalyst flows. The catalyst from the lower zone of the particle transfer apparatus is conveyed to the reactions zone.
