Abstract
An apparatus provides for increased feed throughput without loss of conversion or selectivity by increasing the catalyst volume in a final reactor of at least three reaction zones. The catalyst volume of the final reactor may be larger because the inner and outer screens that define a radial flow bed are extended. A low LHSV is maintained by increasing the catalyst volume in the final reactor.
