    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.The improved technique comprises 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 + components; reacting C.sub.3 + 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.4 + isoparaffin for recycle to the sorption zone as lean sorbent; and recovering C.sub.7 + alkylate product from the process.

    摘要: Olefin upgrading in plural reactors can achieve conversion of lower olefinic feedstock, such as propene, butene, etc., to valuable heavy hydrocarbons containing a lubricant fraction of high viscosity index. Other fuel products, such as (C.sub.10 -C.sub.20) distillate, gasoline and LPG may also be recovered as products. In a preferred process for converting lower olefinic feed to heavier hydrocarbons by contacting the feed with a shape selective medium pore acidic zeolite catalyst at elevated temperature and pressure the catalyst surface is rendered relatively inactive by adding to the olefinic feed an inactivating amount of a sterically-hindered organic base, whereby the catalyst is selectively surface-deactivated, to produce substantially linear heavier hydrocarbons rich in C.sub.10.sup.+ olefins. In the preferred multi-stage process the olefinic feed comprises C.sub.2 -C.sub.8 olefins and the catalyst employed in each stage comprises aluminosilicate having a silica-to-alumina mole ratio of at least 12 and a constraint index of about 1 to 12.

    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.
