    摘要: Apparatus is disclosed for oligomerizing olefinic Fischer-Tropsch liquids to produce heavier hydrocarbons by converting olefinic feedstock containing oxygenated hydrocarbons over an acidic zeolite catalyst. The improvement comprises an extraction unit for removing oxygenates from the feedstock; means for converting the extracted feedstock in a primary stage distillate mode catalytic reactor system under low severity conditions at high pressure and moderate pressure; means for recovering the oxygenates and light hydrocarbons from the primary stage and a secondary stage reactor system for conversion of oxygenates under high severity conditions at substantially higher temperature than the primary stage, thereby converting oxygenates and light hydrocarbons to heavier hydrocarbons.
