A catalytic distillation process for isomerizing and separating 1-alkenes from a mixed alkene stream. The process comprises contacting a mixed alkene stream comprising the 1-alkene and homologs thereof with a supported isomerization catalyst under isomerization/distillation conditions effective to convert at least a portion of the homologs to the 1-alkene, the isomerization/distillation conditions also being effective to produce a distillation overhead comprising a sufficient portion of the 1-alkene to drive isomerization of the homologs to the 1-alkene while maintaining the mixed alkene stream at least partially in liquid phase. The isomerization/distillation conditions are effective to recover a quantity of 1-alkene greater than an equilibrium quantity of 1-alkene recovered under isomerization conditions alone. The 1-alkene is selected from the group consisting of 1-alkenes having from about 4 to about 8 carbon atoms; provided that, when the mixed alkene stream is a Cstream, the isomerization/distillation conditions comprise an amount of an extraction agent.

The present invention relates to a novel aqueous-phase oxidizer and solids separator reactor. More particularly, the invention relates to a two zone pressure vessel in which precipitates and other solids fall or are sprayed from a supercritical temperature super zone into a lower temperature sub zone. The feed material may consist of various waste products which are subsequently oxidized in the super zone of the pressure vessel. The resultant brine or slurry which is found at the lower temperature sub zone of the vessel is removed via a pipe and disposed of accordingly.
