Abstract

See full text

A method for producing an isoolefinic stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit comprising a serial reactor and a lights removal column, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; and wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; and oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce the isoolefinic stream.
