Abstract:
Producing C5 olefins from steam cracker C5 feeds 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 fraction comprising the C6+ hydrocarbons and dicyclopentadiene and a second fraction comprising C5 olefins and C5 dienes. The second fraction, a saturated hydrocarbon diluent stream, and hydrogen may be fed to a catalytic distillation reactor system for concurrently separating linear C5 olefins from saturated hydrocarbon diluent, cyclic C5 olefins, and C5 dienes contained in the second fraction and selectively hydrogenating C5 dienes. An overhead distillate including the linear C5 olefins and a bottoms product including cyclic C5 olefins are recovered from the catalytic distillation reactor system. Other aspects of the C5 olefin systems and processes, including catalyst configurations and control schemes, are also described.

Claim (Index 27):
A process for producing C5 olefins from a mixed C5 feed, the process comprising:\n feeding hydrogen and a mixed hydrocarbon stream comprising cyclopentadiene, linear C5 olefins, cyclic C5 olefins, and C6+ hydrocarbons to a catalytic distillation reactor system; concurrently in the catalytic distillation reactor system:\n separating the linear C5 olefins from the cyclic C5 olefins, C5 dienes, and C6+ hydrocarbons; and \n selectively hydrogenating at least a portion of the C5 dienes to form additional linear C5 olefins; \n withdrawing a liquid side draw from a stage below a mixed hydrocarbon feed location and a hydrogen feed location and above a main reboiler, at least partially vaporizing the liquid side draw in an intermediate reboiler, and returning the at least partially vaporized liquid side draw to the catalytic distillation reactor system; recovering linear C5 olefins as an overhead distillate from the catalytic distillation reactor system; and recovering cyclic C5 olefins as a bottoms product from the catalytic distillation reactor system.
