Mass percent product distributions of (a) olefins and (b) carbenium ions for the oligomerization of C4 olefins up to C16 at 67% of conversion. Feed composition is 50% iso-butene, 25% 1-butene and 25% 2-butene. The initial molecular population is 100,000. In the two limited reaction networks, the PCP steps are not considered and the protonation/deprotonation equilibrium is also considered in the DLRN.
