ABSTRACT:
In the conversion of light olefins to heavier hydrocarbons, an improved recovery technique is provided for selectively removing unreacted light olefins from a catalytic reactor effluent. This system is useful in converting ethene-rich feedstocks to gasoline and/or distillate products, particularly in oligomerization processes employing shape selective siliceous catalysts such as ZSM-5 type zeolites. By recycling gasoline-range hydrocarbons as a sorbent liquid, unreacted C.sub.2.sup.+ components may be absorbed from reactor effluent vapor and returned for further contact with the catalyst.
