1. A process for oligomerizing an olefin stream comprising:
charging a C2 vapor olefin stream and a C3+ liquid olefin stream to a first-stage oligomerization reactor, comprising a first-stage oligomerization catalyst, to produce a first-stage oligomerized stream; and
oligomerizing said first-stage oligomerized stream in a second-stage oligomerization reactor, comprising a second-stage oligomerization catalyst, to produce a second-stage oligomerized stream,
wherein said first-stage oligomerization catalyst is different from said second-stage oligomerization catalyst.
