摘要： 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.

摘要： Systems and processes for the treatment of a naphtha range hydrocarbon feedstock comprising sulfur-containing compounds, nitrogen-containing compounds, olefins, diolefins, and aromatics. The systems and processes are configured to treat the naphtha range hydrocarbon feedstock to convert the sulfur-containing compounds, nitrogen-containing compounds, and olefins, diolefins while less than 2 wt % aromatics are hydrogenated, producing an olefin lean overheads fraction comprising less than 0.2 wt % olefins and less than 100 mg/kg sulfur and an aromatics rich fraction comprising less than 50 ppmw olefins, less than 0.5 ppmw sulfur and less than 0.5 ppmw nitrogen.
