Abstract
An axial flow staged zone oligomerization reaction process includes the steps of passing a hydrocarbon feedstock into the lower portion of the axial flow staged zone reactor which includes axial circulation of the hydrocarbon reaction fluid serially in each of the reaction zones, passing catalyst through a constriction zone located between successive upper and lower catalytic reaction zones which includes heat exchanging of the fluids being the constriction zone within the reactor and further includes withdrawing the oligomerized product from the top of the reactor.
