    摘要: A continuous multistage catalytic conversion system for upgrading lower olefins comprisingfirst adaibatic catalytic bed reactor means containing an acidic zeolite solid catalyst;means for feeding light olefinic gas directly to the first reactor without addition of separate diluent or recycle streams;means for operating the first reactor under olefin partial conversion conditions at elevated temperature to control adiabatic temperature increase;interstage quench means for injecting a liquid coolant directly into first stage effluent for reducing the temperature thereof and protecting downstream catalyst;second catalytic bed reactor means for receiving cooled first stage effluent with injected liquid coolant and further converting the olefins over a metallic zeolite catalyst having a metal ethene oligomerization component;means for cooling and recovering heavier liquid hydrocarbon product from the second reactor effluent; andmeans for recovering liquid coolant from the second effluent for recycle to the interstage quench means.

    摘要: A continuous multi-stage catalytic process for converting ethene-rich lower olefinic feedstock to heavier liquid hydrocarbon product, comprising the steps ofcontacting ethene-rich feedstock at elevated temperature and moderate pressure in a primary stage reaction zone with a first catalyst comprising shape selective medium pore zeolite to convert at least a portion of the lower olefinic components to intermediate olefinic hydrocarbons;cooling primary stage reaction effluent by introducing a stream of cold water sufficient to reduce the primary stage effluent to second stage reaction temperature; andcontacting unreacted ethene and at least a portion of the intermediate olefinic hydrocarbons from the primary stage with nickel-containing shape selective medium pore zeolite oligomerization component at elevated temperature to provide a heavier hydrocarbon effluent stream comprising gasoline and/or distillate range hydrocarbons.
