Propylene contained in mixed C3/C4 streams containing at least 5 wt. % isobutene, for example, catalytic cracker offgas, may be recovered as a useful gasoline component by oligomerizing the propylene in liquid phase at 80 DEG to 130 DEG C. at LHSV 2 to 5 in the presence of an acidic cation exchange resin whereby the oligomers produced are primary C6 to C8 mono olefins.
