    摘要: Aliphatic oxygenates are converted to high octane gasoline by an integrated reactor system wherein three reaction zones are utilized. In a first reaction zone the oxygenates are directly converted to gasoline and an isobutane by-product. In a second reaction zone oxygenates are dehydrated to an intermediate product comprising C.sub.3 -C.sub.4 olefins, which are then further reacted with the isobutane by-product in a third reaction zone to yield a gasoline alkylate. Ethylene-containing vapors may be separated from the second reaction zone and recycled to the first reaction zone for further processing.

    摘要: Alkylate is produced by catalytically converting oxygenate feedstock, such as methanol, to lower olefins comprising C.sub.2 -C.sub.4 olefins. Ethene is separated by interstage sorption of C.sub.3 + components and an isoparaffin is alkylated with C.sub.3 -C.sub.4 olefins derived from sorbate. The system comprises means for fractionating an olefinic feedstream containing ethene and C.sub.3 + olefinic components by contacting the olefinic feedstream in a sorption zone with a liquid hydrocarbon sorbent to selectively sorb C.sub.3.sup.+ components; means for reacting C.sub.3.sup.+ olefins with excess isoparaffin in a catalytic alkylation reactor to produce C.sub.7 + alkylate hydrocarbons; fractionating the alkylation reactor effluent to provide a liquid hydrocarbon fraction rich in C.sub.7.sup.+ alkylate. Liquid recycle or C.sub.5.sup.+ liquid coproduced with the lower olefin may be passed to the sorption zone as lean sorbent. C.sub.7.sup.+ alkylate product and C.sub.5.sup.+ gasoline are recovered from the process.

    摘要: A technique for continuous conversion of diene-containing aliphatic hydrocarbon feedstock to heavier hydrocarbon products wherein the feedstock is contacted at elevated temperature under endothermic high severity reaction conditions with a fluidized bed of acidic zeolite fine catalyst particles, comprising methods and means for:maintaining the fluidized catalyst bed in a vertical reactor having a turbulent reaction zone by passing vapor upwardly through the reaction zone at a velocity greater than dense bed transition velocity to a turbulent regime and less than transport velocity for the average catalyst particle;feeding a continuous stream of feedstock into the reaction zone, said feedstream comprising sufficient C.sub.3.sup.+ alkanes to require net endothermic reaction conditions;withdrawing a portion of coked catalyst from the reaction zone, oxidatively regenerating the withdrawn catalyst, heating the catalyst substantially above process temperature in the fluidized bed reactor, and returning hot regenerated catalyst to the reaction zone at a rate to control catalyst activity and reaction temperature under conditions of reaction severity to effect feedstock conversion to an aromatics-rich hydrocarbon effluent stream; andseparating an aromatics-rich product from the fluidized bed effluent stream.Aromatics yield is increased by recovering a recycle stream comprising C.sub.5.sup.+ aliphatic hydrocarbons from the fluidized bed effluent stream for further conversion in the fluidized bed to increase aromatics product yield.
