    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.

    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.
