    摘要: An improved fluidized bed process for upgrading olefinic hydrocarbon feedstock by contacting the feedstock with acidic siliceous zeolite conversion catalyst particles at elevated temperature under exothermic conditions to produce heavier hydrocarbons including gasoline range hydrocarbons. The improvement comprises maintaining a turbulent fluidized bed of catalyst particles by flowing hydrocarbon-containing vapor upwardly through said bed at less than transport velocity; and introducing liquid olefinic feedstock comprising at least one C.sub.4 -C.sub.6 diene component into the fluidized catalyst bed in a lower portion thereof by rapidly atomizing and vaporizing the liquid feedstock, thus converting feedstock to heavier hydrocarbon without substantial thermal diene degradation thereof prior to contacting conversion catalyst particles in the fluidized bed. A predominantly liquid product is recovered containing C.sub.4 -C.sub.9 hydrocarbons rich in olefins and aromatics.

    摘要: Disclosed is a method and apparatus for producing gasoline and distillate grade products which employs integrating catalytic (or thermal) dehydrogenation of paraffins with MOGD to minimize interstage compression and gas plant separation cost. The process cascades the product from a low temperature propane or butane dehydrogenation zone into a first catalytic reactor zone which operates at low pressure and contains zeolite oligomerization catalysts, where the low molecular weight olefins are reacted to primarily gasoline range materials. These gasoline range materials can then be pressurized to the pressure required for reacting to distillate in a second catalytic reactor zone operating at high pressure and containing zeolite oligomerization catalyst. The first catalytic reactor zone also acts to remove the olefins from the dehydrogenation reactor effluent to allow recycle of the unreacted paraffins.

    摘要: An apparatus for converting oxygenated feedstock, such as methanol, dimethyl ether or the like, to liquid hydrocarbons. In the primary catalyst stage the feedstock is contacted with a fluidized zeolite catalyst to produce C.sub.2 -C.sub.4 olefins and C.sub.5.sup.+ hydrocarbons. In a secondary catalytic stage with oligomerization catalyst comprising medium-pore shape selective acidic zeolite at increased pressure converts C.sub.3.sup.+ olefins to gasoline and/or distillate liquids. A portion of the recovered gasoline stream is recycled to the fluidized bed at a point above the bed stratum corresponding to substantially complete oxygenate conversion.
