    摘要: An oligomerization system is provided for upgrading lower olefins to distillate hydrocarbons, especially useful as high quality jet or diesel fuels. The olefinic feedstock is reacted over a shape selective acid zeolite, such as ZSM-5, to oligomerize feedstock olefins and further convert recycled hydrocarbons. Reactor effluent is fractionated to recover a light-middle distillate range product stream and to obtain gasoline and heavy hydrocarbon streams for recycle.

    摘要: Olefin undergoes conversion in the presence of water to a mixture of alcohol and ether which is then subjected to various downstream operations including distillation and decantation to provide an ether-rich product containing little if any water. If desired the ether can be combined in any predetermined ratio with co-produced alcohol to provide alcohol/ether mixtures of desired composition. The foregoing process is especially suitable to the conversion of propylene and propylene-containing streams to diisopropyl ether and mixtures of isopropyl alcohol and diisopropyl ether which are useful, inter alia, as octane improves for gasoline.

    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: A multistage process for producing isoalkyl ethers from lower aliphatic oxygenate feedstock, such as methanol. Feedstock is catalytically converted in a primary catalyst stage at elevated temperature in contact with zeolite catalyst to predominantly C.sub.2 -C.sub.7 lower olefins comprising isobutylene and isoamylene, by-product water and a minor amount of C.sub.8.sup.+ hydrocarbons, followed by fractionation of the C.sub.2 -C.sub.7 olefins to recover a C.sub.2 -C.sub.3 -rich recycle stream for further catalytic conversion in the primary stage. C.sub.4 -C.sub.7 olefins are passed to a second catalytic etherification stage for reaction of isoalkenes with methanol to produce methyl tertiary-butyl ether, methyl isoamylether and higher isoalkyl ethers. The second stage effluent may be fractionated to recover an ether product, C.sub.5.sup.+ hydrocarbon liquid product, and unreacted butenes. Advantageously, the unreacted butenes are further reacted with isoparaffin in a third catalytic stage under acid catalysis alkylation conditions, and fractionated to recover C.sub.6.sup.+ alkylate liquid, liquid hydrocarbon product. The ethers may be blended with at least one C.sub.6.sup.+ hydrocarbon to produce high octane gasoline.
