Abstract:
1. A reactor system including a series of reactors, the reactor system comprising: a first reactor for contacting a feed with a first catalyst bed in the first reactor, at least one intermediate reactor for contacting an effluent from the first reactor with an intermediate catalyst bed in the at least one intermediate reactor; and a final reactor for contacting an intermediate effluent from a last one of the at least one intermediate reactor with a final catalyst bed in the final reactor, a transfer line for adding catalyst to the top of the final catalyst bed and a transfer line for withdrawing catalyst from the bottom of the final catalyst bed in the final reactor, the final reactor being located to the side of the at least one intermediate reactor and the catalyst bed of the final reactor having an inner and outer screen retaining the final catalyst bed therebetween for the radial flow of reactants, said outer screen being extended to a distance that will increase the volume of catalyst at least 5% greater than the first catalyst bed.
