The production of C5 olefins from a steam cracker C5 feed may include reacting a mixed hydrocarbon stream comprising cyclopentadiene, C5 olefins, and C6+ hydrocarbons in a dimerization reactor, where cyclopentadiene is dimerized to dicyclopentadiene. The dimerization reactor effluent may be separated into a first fraction comprising C6+ hydrocarbons and dicyclopentadiene and a second fraction comprising C5 olefins and C5 dienes. The second fraction, the saturated hydrocarbon diluent stream, and hydrogen may be fed to a catalytic distillation reactor system to simultaneously separate linear C5 olefins from the saturated hydrocarbon diluent, cyclic C5 olefins contained in the second fraction, and C5 dienes; and the C5 dienes are selectively hydrogenated. An overhead distillate comprising linear C5 olefins and a bottoms product comprising cyclic C5 olefins are recovered from the catalytic distillation reactor system. Other aspects of the C5 olefin system and method are also described, including catalyst configuration and control schemes.)
