摘要： A process control technique for upgrading C.sub.3 -C.sub.4 hydrocarbon feed containing olefins to produce heavier liquid hydrocarbons comprising converting a major portion of C.sub.3 -C.sub.4 olefins in an oligomerization zone by contacting a shape selective medium pore zeolite catalyst at elevated temperature and pressure to make distillate and olefinic gasoline. The oligomerization stage effluent is fractionated to provide distillate and gasoline product and a C.sub.3 -C.sub.4 intermediate stream containing isobutane and unconverted propene and butylene. The C.sub.3 -C.sub.4 intermediate stream is combined under control with a portion of C.sub.3 -C.sub.4 feed and further converting the combined streams in an alkylation zone to make heavier paraffinic hydrocarbons. The olefin feed may be produced by catalytically converting methanol or similar oxygenated hydrocarbons in a known process. Controlled material balance is achieved by accumulating liquid olefin feed to the oligomerization and akylation units using a surge drum with liquid level control. By-product isobutane is recovered and recycled under liquid level control operatively connected to determine feed of liquid olefin to the conversion units.

摘要： Aliphatic oxygenates are converted to high octane gasoline by an integrated process 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： High viscosity lubricants are formed by oligomerizing olefins in two stages. The first stage converts a lower olefin feed to distillate range hydrocarbons in the presence of an aluminosilicate zeolite such as ZSM-5. The distillate effluent from the first stage is further polymerized to lubricant range hydrocarbons at elevated temperatures in the presence of a ditertiary alkylperoxide catalyst.

摘要： Light olefins are co-processed with aromatic-containing jet fuel range distillate over a large pore zeolite to produce an olefinic distillate and a high molecular weight alkyl aromatic fraction higher boiling than the olefinic distillate. The alkyl aromatic fraction is of high cetane value and can be separated from the olefinic distillate and used as blending material for diesel fuel.

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.
