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： A catalytic process for converting an olefinic feedstock comprising lower olefin to heavier hydrocarbon product comprising the steps of:contacting the feedstock and a recycled hydrocarbon with shape-selective zeolite oligomerization catalyst in catalytic reaction zone at elevated temperature and pressure to provide a heavier hydrocarbon effluent stream comprising heavy, intermediate and light hydrocarbons;flashing the effluent stream between the reaction zone and a phase separation zone by reducing pressure of the effluent stream, thereby producing a heavy liquid stream rich in heavy hydrocarbons and a flashed effluent vapor stream containing lighter hydrocarbons;separating and recovering a recycle stream rich in intermediate range hydrocarbons from the separation zone and pressurizing the recycle stream for recycle to the reactor inlet;further fractionating the heavy liquid stream and flashed effluent vapor from the phase separation zone in first distillation tower to remove light hydrocarbons therefrom; andrecovering substantially all of the heavy hydrocarbons produced in the reaction zone in a fractionated liquid product stream.

摘要： A multi-stage catalytic olefin upgrading technique for converting lower olefinic feedstock to heavier liquid hydrocarbon product. The invention provides a fluid bed continuous primary stage reaction zone with shape selective medium pore zeolite oligomerization catalyst particles to convert at least a portion of the lower olefinic components to intermediate olefinic hydrocarbons containing olefinic and aromatic components; cooling primary stage reaction effluent to condense at least a portion of the intermediate hydrocarbons; feeding a second olefinic stream to a serially arranged multi-reactor secondary stage for upgrading lower olefins; quenching partially upgraded secondary stage olefins with primary stage liquid; and further contacting the quenched mixture including aromatics from the primary stage with shape selective medium pore zeolite olgiomerization catalyst in a high pressure fix bed secondary stage distillate mode catalytic reactor at elevated temperature and high prssure to provide a heavier hydrocarbon effluent stream comprising distillate hydrocarbons.
