Systems and processes for hydrocarbon conversion are provided that utilize a plurality of moving bed reactors. The reactors may be moving bed radial flow reactors. Optional mixers that mix a portion of a second hydrocarbon feed with the effluent stream from an upstream reactor, to produce reactor feed streams may be employed, and the reactor feed streams may be introduced at injection points prior to each reactor. Catalyst can be provided from the reaction zone of one reactor to the reaction zone of a downstream reactor through catalyst transfer pipes, and can be regenerated after passing through the reaction zones of the reactors. The moving bed reactors can be stacked in one or more reactor stacks.
