    Abstract: A method of producing hexene includes: passing a feed stream comprising C 1 to C 24 hydrocarbons through a distillation column, wherein a reflux ratio of the distillation column is greater than or equal to 1.33; distributing a light fraction comprising C 4 -C 6 hydrocarbons to a top portion of the distillation column; distributing a heavy fraction comprising C 8 -C 12 hydrocarbons to a bottom portion of the distillation column; and withdrawing a top product comprising hexene from the distillation column.

    Abstract: Methods of converting olefins include the steps of providing propane and isobutane to a dehydrogenation reactor to produce effluent that is sequentially cooled, compressed and passed to a distillation zone under conditions to fractionate propylene, isobutylene, butane and propane from the effluent. Propylene, isobutylene, butane and propane are separated in a distillation zone to produce a propylene concentrate stream, an isobutylene concentrate steam, a propane recycle stream, and a butane recycle. The propane and isobutane are recycled back into the feed stream. The propylene concentrate stream and the isobutylene concentrate stream are passed to an oligomerization reactor to produce an oligomer product mixture that includes the olefin conversion products. The oligomer product mixture is then passed to the distillation column where olefin conversion product is separated as oligomer product.
